Stem Cell Therapy for Back Pain: How Bone Marrow Concentrate Injections Actually Work
A Patient's Path Back to an Active Life
Dr. Ilana Etelzon of Pain Doctors Medical shares a case that reflects what she sees often in her practice: a patient who had tried nearly everything before finding her way to regenerative medicine.
A 55-year-old woman presented to our office with chronic lower back pain radiating into both legs. She had been struggling with persistent symptoms for several years despite extensive conservative treatment, including physical therapy, physician-directed home exercises, activity modification, anti-inflammatory medications, and multiple epidural steroid injections. Although the injections provided only temporary relief, her pain consistently returned, limiting her quality of life.
The patient reported significant difficulty performing everyday activities such as cooking, grocery shopping, hiking, traveling, and caring for her family. She wished to avoid additional steroid injections and was reluctant to undergo spine surgery.
After a comprehensive evaluation, including a detailed physical examination and review of her imaging studies, she was determined to be an appropriate candidate for a minimally invasive regenerative treatment designed to address the underlying source of her pain rather than simply mask the symptoms.
Over the weeks following treatment, she experienced progressive improvement in both her lower back pain and the pain radiating into her legs. As her recovery continued, she was able to return to the activities she enjoyed most, including cooking, hiking, traveling, and caring for her family without significant limitations. She no longer required pain medications, additional physical therapy, or further steroid injections.
Most importantly, she was able to avoid spine surgery while regaining an active lifestyle and a substantially improved quality of life. She expressed tremendous satisfaction with her outcome and was grateful to return to living life on her own terms.
The treatment behind this recovery is a bone marrow concentrate injection, often called BMAC. The procedure draws a small sample of the patient's own bone marrow, concentrates the cells and growth factors within it, and delivers that concentrate directly to the site of injury using image guidance. For patients who want to avoid spine surgery and long term reliance on steroid injections, it offers an option that targets the source of the pain instead of covering it up.
The Pain Doctors Medical Approach to BMAC
Dr. Etelzon is a Regenexx Certified Core Provider, a distinction that shapes how her practice performs bone marrow concentrate injections from start to finish.
One of the biggest differences in our approach is that we don't simply perform a bone marrow concentrate (BMAC) injection. We follow a comprehensive, evidence-informed protocol designed to maximize precision and optimize the biologic environment for healing.
As a Regenexx Core Provider, I have undergone extensive advanced training in image-guided orthobiologic procedures and follow standardized protocols developed through years of clinical experience and ongoing research. Every patient undergoes a thorough evaluation to determine whether regenerative treatment is appropriate and to identify the specific structures responsible for their pain. Careful patient selection is one of the most important factors in achieving successful outcomes.
Our procedures are performed using high-resolution ultrasound and fluoroscopic guidance to ensure accurate placement of the biologic into the intended target tissues. Rather than treating only a single painful area, we frequently evaluate and address all of the structures contributing to dysfunction, including joints, ligaments, tendons, muscles, and, when appropriate, the spine, creating a comprehensive treatment plan tailored to the individual patient.
Another key difference is our attention to biologic preparation and rehabilitation. Bone marrow concentrate is processed according to established protocols, and treatment is often complemented by platelet-rich plasma (PRP), platelet lysate, or platelet-poor plasma (PPP) when clinically indicated. Patients also receive individualized rehabilitation guidance, activity modification, and follow-up to support recovery and optimize long-term function.
Being a Regenexx Core Provider does not guarantee a particular outcome, and no regenerative treatment is effective for every patient. However, it does mean that patients are treated using standardized protocols, advanced image-guided techniques, rigorous training standards, and an evidence-informed approach that emphasizes precision, safety, and appropriate patient selection. These principles are designed to give patients the best opportunity for a successful outcome while helping many avoid or delay more invasive procedures when clinically appropriate.
When Surgery Is Still the Right Path
Regenerative treatment is not the answer for every patient, and Dr. Etelzon is candid about where its limits are and how she determines the right course for each person she sees.
One of the most important conversations I have with every patient is understanding that regenerative medicine is incredibly powerful, but it is not the right solution for everyone. My responsibility is not simply to perform a procedure: it's to determine whether that procedure gives the patient a realistic chance of avoiding surgery.
There are situations where regenerative treatment alone is unlikely to provide the desired outcome. Patients with progressive neurologic weakness, significant spinal instability, severe deformity, advanced joint destruction, certain complete tendon ruptures, infections, fractures requiring stabilization, or conditions such as cauda equina syndrome often require prompt surgical evaluation. In these cases, delaying surgery could actually worsen the outcome.
The key is determining why the patient has pain. I spend considerable time reviewing imaging, performing a comprehensive physical examination, and correlating the two. I want to identify the true pain generators, not just the abnormalities seen on an MRI. Many patients are told they need surgery based solely on imaging, yet their symptoms may actually arise from treatable ligaments, tendons, joints, muscles, or other structures that have never been properly evaluated.
When appropriate, we take a comprehensive, precision-based approach. Rather than focusing on a single painful spot, we evaluate the entire functional unit and address all of the structures contributing to the patient's symptoms. That may include treating joints, supporting ligaments, tendons, muscles, and other stabilizing tissues using advanced image-guided regenerative techniques, combined with individualized rehabilitation, activity modification, and ongoing follow-up. The goal is not simply pain relief, it is restoring function and improving the body's ability to heal.
Only after I am confident that we have appropriately evaluated the patient and determined whether a regenerative approach is likely to help do we discuss treatment. If I believe surgery offers the best chance for recovery, I will tell my patient that honestly and refer them to an appropriate surgeon. My priority has always been doing what is best for the patient, even when that means recommending against a procedure in my own office.
For many carefully selected patients, regenerative medicine can help reduce pain, improve function, and potentially delay or avoid surgery. However, the best outcomes come from proper diagnosis, meticulous patient selection, precise image-guided treatment, and knowing when regenerative medicine has reached its limits. That commitment to individualized care is what allows us to confidently pursue every reasonable option before recommending surgery while never compromising patient safety.
Finding Out If You're a Candidate
Pain Doctors Medical evaluates candidates for bone marrow concentrate injections and other regenerative treatments at its Brooklyn, Clifton, Newark, and Perth Amboy locations. A consultation with Dr. Etelzon includes a review of imaging, a physical examination, and an honest conversation about whether regenerative medicine is the right next step, or whether a surgical referral makes more sense.

Regenerative Medicine for Shoulder Pain: Can You Actually Avoid Surgery?
Shoulder pain has a habit of quietly editing a life. The overhead reach for a coffee mug, the swing on the back nine, lifting a grandchild off the ground, these movements start to feel like negotiations instead of small, automatic moments. For many women in their fifties, sixties, and seventies, regenerative medicine is changing what comes next, offering a path back to those movements that do not start with a surgical consult.
Regenerative medicine for shoulder pain uses concentrated platelets or bone marrow-derived cells, drawn from the patient's own body, to target the specific tendon, ligament, or joint tissue causing the problem. For rotator cuff tendinopathy, partial tears, and early arthritic changes, this approach gives the tissue the biologic material it needs to repair itself, rather than removing or replacing what is already there. That is the appeal driving so many patients to research this option before they ever book a surgical consultation.
At Pain Doctors Medical, this approach is led by Dr. Ilana Etelzon, MD, a double board-certified interventional pain and physical medicine and rehabilitation physician and a certified Regenexx Core Provider. Shoulder pain is one of the most common reasons patients come to her for regenerative medicine, and her process for getting there starts with a real diagnosis, not a sales pitch.
A Diagnosis Comes Before Any Treatment Decision
"Every shoulder pain patient undergoes a detailed evaluation, including a physical exam, diagnostic ultrasound, and imaging review when needed," Dr. Etelzon explains. "The goal is to identify the exact source of pain before considering treatment."
Ideal candidates are patients with tendon, ligament, labral, or arthritic conditions that have not responded to conservative care. Complete tears requiring surgery, active infection, and severe joint destruction typically rule a patient out for regenerative treatment, which is part of why the evaluation matters as much as the procedure itself.
PRP or PRP With Bone Marrow Concentrate: The Decision Behind the Decision
"PRP alone is often an excellent option for milder rotator cuff tendinopathy and small partial tears," says Dr. Etelzon. For more significant tissue degeneration, larger partial tears, prior treatment failures, or patients looking to maximize healing potential, she may recommend adding bone marrow concentrate.
"Age and activity level do play a role," she notes. "An active athlete in their 40s with a substantial partial tear may benefit from a more robust biologic approach than a less active patient with mild tendinopathy." The decision ultimately comes down to the severity of the tissue damage, the patient's healing goals, and their overall activity demands.
Why MLS Laser Therapy Is Often Paired With the Injection
"Regenerative injections help provide the biologic building blocks for healing, while MLS laser therapy creates a more favorable healing environment," Dr. Etelzon explains. In practice, that often means performing the injection first, then following it with MLS laser treatments over the next several weeks to reduce inflammation, improve circulation, support cellular metabolism, and enhance tissue recovery.
"The goal isn't simply pain relief. It's to optimize the body's healing response," she says. The injection addresses the injured tissue directly, and the laser helps accelerate and support the recovery process, which is why the two are frequently used together in appropriate patients.
Cutting Through the Marketing Noise Around Stem Cells
"For many patients, the confusion comes from marketing," Dr. Etelzon says. She is direct with patients about what bone marrow concentrate actually is: "Bone marrow concentrate is not a magic cure, and it's not about growing a brand new shoulder. It's a concentration of the body's own repair cells, growth factors, and signaling molecules designed to support the natural healing process."
Her advice to patients is to "be skeptical and focus on the diagnosis, the quality of the procedure, and the available evidence, not the advertising." She frames the real goal of treatment as improving the biologic environment, reducing pain, enhancing function, and potentially delaying or avoiding more invasive treatment for the right candidate. Setting realistic expectations, she says, is one of the most important parts of the consultation.
What Recovery Actually Looks Like
"Recovery after regenerative treatment is generally much easier than recovery after surgery, but it's important for patients to understand that healing still takes time," Dr. Etelzon says. Most patients notice some soreness for several days after the procedure as the body's healing response gets underway. Over the first few weeks, the focus shifts to protecting the treatment area, restoring motion, and gradually increasing activity. There are no incisions, no implants, and typically no prolonged immobilization.
"Most patients can continue many of their normal daily activities within days, while meaningful improvements often develop gradually over the following weeks to months as the tissue heals," she explains. The biggest difference from surgery is the absence of a long rehabilitation period built around recovering from the procedure itself.
Getting Back to What Matters
For the women who come through Pain Doctors Medical's doors in Brooklyn, Clifton, Newark, and Perth Amboy, shoulder pain is rarely just about the shoulder. It's about the swim laps put off for months, the garden beds that have become too hard to kneel into, the grandchildren they want to lift without wincing. Regenerative medicine gives many of them a way back to those moments, with a recovery that fits into real life instead of replacing it for months.
If shoulder pain has started limiting what matters most, a consultation with Dr. Etelzon is a clear and simple next step.
What Is Regenerative Medicine and Is It Right for You?
Regenerative medicine is reshaping how physicians and patients think about healing. Rather than managing pain from the outside in, it works from the inside out, using the body's own biology to repair damaged tissue, restore function, and help people get back to the activities that make life worth living.
For patients who have spent years cycling through treatments that offer temporary relief but never quite solve the problem, regenerative medicine offers something different: a path toward actual healing.
Dr. Ilana Etelzon, MD, a double board-certified interventional pain specialist and Regenexx Core Provider at Pain Doctors Medical, has built her practice around this approach. Here, she explains what regenerative medicine actually does, how it works, and why the outcomes consistently go beyond what patients expect.
It Aims to Heal the Tissue, Not Just Quiet the Pain
Most patients arrive at Pain Doctors Medical having tried treatments that focused on managing their symptoms. That approach can be valuable. But it does not address what is actually wrong.
"Most treatments focus on managing symptoms," Dr. Etelzon says. "Regenerative medicine focuses on helping your body heal the underlying injury."
In practice, that means using the body's own healing cells and growth factors to support tissue repair, improve function, and potentially help patients avoid more invasive interventions. The goal is not temporary relief. It is helping the damaged area function better over the long term.
That distinction matters more than it might seem. Chronic pain is often a symptom of tissue dysfunction, not just a signal to be turned down. When the tissue itself heals, patients tend to experience more durable improvements, not just in pain levels but in what they can actually do.
What Is Actually Happening at the Tissue Level
One of the most common questions Dr. Etelzon gets is how regenerative treatments are different from a cortisone injection. The short answer: cortisone reduces inflammation and can provide meaningful relief, but it does not repair anything. Used repeatedly, it may actually have negative effects on tissue health over time.
Regenerative treatments work differently. They deliver concentrated growth factors and healing signals that help the body recruit repair cells, improve blood flow, and support the healing response within injured tissues. Tendons, ligaments, joints, and cartilage are given a biological environment in which they can recover.
"What many patients don't realize is that pain is often a symptom of tissue dysfunction," Dr. Etelzon explains. "While cortisone can quiet the pain signal, regenerative medicine aims to improve the health of the tissue itself, which may lead to more durable improvements in pain and function."
The Four Treatments at Pain Doctors Medical
At Pain Doctors Medical, Dr. Etelzon uses four core regenerative and supportive modalities: platelet-rich plasma (PRP) injections, bone marrow concentrate (often referred to as stem cell therapy), MLS laser therapy, and shockwave therapy. What sets her approach apart is that she rarely uses just one.
"In many cases, the best results come from combining treatments because healing is multifaceted," she says. "Just as you wouldn't build a house with only one tool, we often use a strategic combination of regenerative procedures and supportive therapies to create the best environment for healing."
Here is how each one works:
PRP injections use a concentrated preparation of the patient's own platelets, rich in growth factors. PRP is often well-suited for mild to moderate injuries and inflammation in tendons, joints, and soft tissue.
Bone marrow concentrate draws on the regenerative cells found in the patient's own bone marrow. It is typically reserved for more advanced degeneration or complex cases where a more potent biological signal is needed.
Shockwave therapy delivers acoustic energy to stimulate healing and improve blood flow, making it particularly useful in chronic tendon injuries that have been resistant to other treatments.
MLS laser therapy uses synchronized wavelengths of light to reduce pain and inflammation and support the recovery process, often used alongside other regenerative procedures.
The treatment plan for each patient starts from scratch. Dr. Etelzon considers the diagnosis, the severity of tissue damage, the patient's goals, and what they have already tried. No two plans look exactly the same.
Why the Regenexx Credential Matters
Regenerative medicine is a field where technique matters enormously. The quality of the biologic product, how it is processed, and the precision of where it is placed can all affect outcomes significantly.
Dr. Etelzon is a Regenexx Core Provider, which means she has completed advanced training in image-guided regenerative orthopedic procedures and follows strict clinical protocols. Regenexx procedures are performed using imaging guidance to accurately target the specific structures involved, rather than injecting a general area.
"It's not just about what is injected," Dr. Etelzon says. "It's about how, where, and why it's done. Those details can make a meaningful difference in the care patients receive."
Patients also benefit from protocols refined over many years and access to one of the largest regenerative medicine outcome databases in existence. That level of rigor is not universal in this space, and it is one reason patients travel to Pain Doctors Medical from across New Jersey and New York.
The Result That Surprises Patients Most
When patients come in, they are hoping their pain will improve. That is usually not the thing that surprises them.
"The biggest surprise is usually not the pain relief. It's getting their life back," Dr. Etelzon says. "I've had patients get back to golfing, hiking, playing tennis, traveling comfortably, exercising, getting down on the floor with their grandchildren, or simply walking without constantly thinking about their pain."
The activities patients describe are rarely extreme. They are things most people take for granted until they cannot do them anymore. A long walk. A flight without dread. A round of golf with friends. Weekend hikes. Time with grandchildren that does not end in pain.
The moment Dr. Etelzon finds most rewarding is when a patient says: "I stopped doing that years ago because I thought I'd never be able to again."
That is the metric regenerative medicine is measured by at Pain Doctors Medical. Not just pain scores. Restored function, restored confidence, and a return to the life the patient had before things started breaking down.
Is Regenerative Medicine the Right Next Step for You?
Regenerative medicine is not a fit for everyone, and Dr. Etelzon will tell you that directly. But for patients who have not found lasting relief through conventional treatments and are looking for an alternative to surgery or long-term medication, it is worth a real conversation.
Pain Doctors Medical sees patients at four locations: Clifton NJ, Newark NJ, Perth Amboy NJ, and Brooklyn NY. Consultations with Dr. Etelzon begin with a thorough evaluation of your history, imaging, and goals before any treatment is recommended.
If you have been quietly adjusting your life around pain for years, it may be time to find out whether there is another option.
What Is MLS Laser Therapy and Can It Relieve Pain Without Surgery?
MLS laser therapy is an FDA-cleared, non-invasive treatment that uses synchronized dual-wavelength light to reduce pain and inflammation and stimulate tissue repair at the cellular level. It works by delivering two specific wavelengths of infrared light simultaneously: one targets inflammation and swelling, the other stimulates cellular energy production, specifically ATP, which is the fuel cells need to repair and regenerate. There are no incisions, no medication, and no recovery time. Most sessions take between 8 and 15 minutes.
For people who have spent months cycling through anti-inflammatories, cortisone shots, and rest without lasting improvement, MLS laser therapy offers a different approach. Rather than blocking pain signals temporarily, it works to change the tissue environment itself, giving the body what it needs to move from chronic irritation toward genuine recovery. At Pain Doctors Medical, with locations in Brooklyn, NY; Clifton, NJ; Newark, NJ; and Perth Amboy, NJ, Dr. Ilana Etelzon typically offers MLS laser therapy as part of a comprehensive regenerative medicine program, most often paired with PRP injections, because the two treatments work together in ways that neither achieves as consistently on its own.
Why MLS Laser Therapy Is Not What Most People Expect
When people hear the word laser, they tend to think of heat. A surgical laser cuts. A cosmetic laser resurfaces. But MLS laser therapy belongs to a different category entirely.
MLS stands for Multiwave Locked System. The technology uses two synchronized wavelengths of light, each doing a distinct job. One wavelength targets inflammation, working to reduce swelling and calm the chemical signals that keep tissue in a reactive state. The other penetrates more deeply to stimulate cellular repair. Together, they create an effect that neither wavelength could produce alone.
The critical distinction is what this light does once it reaches the tissue. Rather than generating heat to stimulate surface circulation, the way a heating pad does, MLS laser energy is absorbed directly by cells. Specifically, it targets the mitochondria, the structures inside each cell responsible for producing ATP, which is the cellular fuel that drives repair, regeneration, and function. When mitochondria are given that light stimulus, they produce more ATP. More ATP means more energy available for healing. The cell is not being tricked into feeling better; it is being given what it needs to actually repair.
The Problem MLS Laser Therapy Is Actually Solving
Chronic pain is rarely just pain. It is almost always a sign that tissue is stuck in a dysfunctional state: inflamed, poorly perfused, structurally compromised, and unable to complete a normal healing cycle. Dr. Etelzon describes this as a tissue environment problem, and it is central to how she approaches treatment.
"Pain is often a signal that tissue is irritated, inflamed, overloaded, or not healing properly," Dr. Etelzon explains. "If we only numb the pain temporarily without improving the health of the tissue, the problem often keeps coming back."
In chronic tendon injuries, joint irritation, soft tissue inflammation, and overuse syndromes, damaged tissue can enter a cycle that is difficult to escape on its own. Persistent inflammation reduces local circulation. Poor circulation limits the delivery of oxygen and nutrients. Without those resources, the tissue cannot repair itself, which leads to ongoing microdamage, increased sensitivity, and eventually a failed healing response. The tissue is not healing; it is simply surviving.
MLS laser therapy is designed to intervene in that cycle. By improving microcirculation, increasing cellular energy production, reducing inflammatory mediators, and supporting lymphatic drainage, it attempts to shift the tissue out of chronic dysfunction and into an environment where recovery is possible.
Who Benefits Most from MLS Laser Therapy
Dr. Etelzon finds MLS laser therapy most valuable when the underlying problem involves irritated, overworked, or slowly healing tissue. Muscles, tendons, ligaments, joints, and nerves all respond to treatment, making it relevant across a wide range of pain presentations.
Patients who have been managing plantar fasciitis for months without real improvement often respond well. So do those dealing with chronic knee or shoulder irritation, tendinopathy that has not resolved with rest or physical therapy, and joint inflammation that keeps flaring despite anti-inflammatory medications. Nerve-related discomfort, including peripheral neuropathy, is another area where MLS therapy has shown benefit, in part because of its effect on improving circulation and reducing the inflammatory environment around nerve tissue.
The patients who tend to arrive at Pain Doctors Medical's Brooklyn, Clifton, Newark, and Perth Amboy locations having exhausted conventional options are often the ones who benefit most. Not because MLS laser therapy is a last resort, but because their conditions are precisely the kind of chronic, slow-to-heal tissue problems the treatment is built to address.
What Treatment Looks Like and When Results Begin
A session is straightforward. The patient is positioned comfortably while a handheld device moves over the treatment area, delivering laser energy through the skin without cutting, without needles, and without any meaningful discomfort. Most people describe feeling mild warmth or a gentle tingling sensation. Sessions are brief, typically lasting between eight and thirty minutes depending on the area being treated, and there is no recovery period afterward.
How quickly a patient notices a difference depends on the nature and duration of the condition.
"Some patients feel relief after one to three treatments, while others notice more gradual improvement over several weeks because the effects are cumulative," Dr. Etelzon notes.
Acute flare-ups or recent injuries often respond after four to six sessions. Chronic tendon or joint conditions commonly require six to twelve. Longstanding degenerative problems may need a longer initial course and periodic maintenance treatments to sustain the improvement.
Why Cortisone Shots and Medications Leave the Underlying Problem Untouched
Patients who have been cycling through cortisone injections and anti-inflammatory medications for months or years without lasting relief are often understandably skeptical that anything short of surgery could help. Dr. Etelzon takes that skepticism seriously, because the treatments they have tried were not ineffective by accident. They are simply designed to do something different.
Cortisone can reduce inflammation quickly, but repeated use does not improve the structural quality of the tissue. Anti-inflammatory medications may blunt symptoms temporarily, but they do not stimulate healing. Rest alone can calm reactive tissue in the short term, but chronically injured tissue that is not actively recovering often becomes weaker and stiffer over time. The underlying cycle of inflammation, poor circulation, and failed repair continues.
"Instead of only asking how we block the pain, the approach becomes: why is the tissue remaining irritated or failing to recover?" Dr. Etelzon explains.
MLS laser therapy is positioned as an answer to that second question. It is not masking a signal; it is attempting to address the reason the signal keeps firing.
MLS Laser Therapy as Part of a Comprehensive Regenerative Program
At Pain Doctors Medical, MLS laser therapy is rarely prescribed in isolation. Dr. Etelzon’s approach is to offer it as part of a comprehensive regenerative program, most commonly paired with PRP injections and, where appropriate, bone marrow concentrate. This is a deliberate clinical decision, not simply a matter of layering treatments. Each component plays a defined role, and they are sequenced with that in mind.
PRP injections deliver concentrated growth factors and biologic signals directly to damaged tissue, prompting the body to initiate a repair response. But the environment surrounding that tissue still matters. Many chronic injuries present with poor circulation, accumulated inflammation, cellular dysfunction, and scar tissue that has built up over time. That environment can limit how well the tissue responds to a regenerative injection, regardless of what the injection delivers.
MLS laser therapy addresses that surrounding environment. Used before or after an injection, it helps improve microcirculation, calm reactive tissue, increase cellular energy production, and support the lymphatic drainage that clears inflammatory debris.
“The injection provides the biologic material and healing signals, while the MLS laser helps create a healthier environment for the tissue to respond and recover,” Dr. Etelzon explains.
When shockwave therapy is also part of the program, it serves a mechanical stimulation role, prompting the tissue to respond to physical stress. MLS laser therapy then supports the recovery phase between shockwave sessions, helping tissue calm down and process the stimulus more efficiently. The result is a program in which each treatment reinforces the others rather than working in parallel.
For patients who want to address the root cause of their pain rather than manage it indefinitely, this structured program approach is where the most meaningful and durable results are typically found.
A Different Starting Point for Chronic Pain
MLS laser therapy is not a cure for every condition, and Dr. Etelzon does not present it as one. But for patients whose tissue is stuck in a state of chronic dysfunction, it offers something that medications and cortisone injections typically cannot: an attempt to change the underlying tissue environment rather than simply respond to the symptom it is producing.
At Pain Doctors Medical's locations in Brooklyn, NY; Clifton, NJ; Newark, NJ; and Perth Amboy, NJ, it is part of a regenerative medicine practice built on the belief that the body has more capacity to heal than conventional pain management typically gives it credit for. For patients who have run out of conventional options without running out of hope, that starting point makes a meaningful difference.
