Nerve hydrodissection may help evaluate or temporarily reduce selected nerve entrapment, irritation, scar-related nerve pain, or complex nerve pain.
Nerve hydrodissection is a minimally invasive procedure used to relieve pain caused by nerve entrapment. Dr. Siefferman explains how ultrasound-guided hydrodissection helps free compressed nerves by separating them from surrounding scar tissue and connective tissue, restoring normal nerve movement.

Hi, I’m Dr. Jason Siefferman, a medical director at Manhattan Pain Medicine and interventional pain specialist. Nerve hydrodissection is a procedure that we will use to free up entrapped nerves.
How do we know if a nerve is entrapped? Sometimes there are functional tests like nerve flossing or nerve gliding activities which will tell us, or we may see it on imaging such as an MRI neurography or ultrasound. If we suspect nerve entrapment, we will first examine the patient thoroughly. If treatment makes sense, nerve hydrodissection is done in the office with ultrasound guidance. Generally, we will use a low-concentration local anesthetic, possibly with low-concentration dextrose and a high volume of fluid to inject around the nerve and separate it from the surrounding fascia which may be entrapping it.
Generally, we only know if the nerve was entrapped after we go in to do the hydrodissection because that’s the process where we will actually see if the fluid does not flow freely around the nerve, and then we can see where we need to target to do the hydrodissection appropriately. At that point, we may add hyaluronidase to dissolve scar tissue or steroid to soften the connective tissue.
Nerve hydrodissection is an ultrasound-guided procedure that uses fluid to gently separate a peripheral nerve from surrounding tissue, fascia, scar tissue, muscle, or other nearby structures when nerve entrapment or mechanical irritation is suspected. It may be considered for selected patients with burning, tingling, shooting, electric, radiating, or focal nerve-like pain.
At Manhattan Pain Medicine, nerve hydrodissection NYC care begins with diagnosis-first evaluation. The goal is to determine whether a specific nerve appears to be involved, whether hydrodissection is appropriate, and how the response may guide next steps in care.
MPM specialists evaluate whether nerve hydrodissection may be appropriate by carefully mapping symptoms to nerve anatomy. Nerve-like pain may come from peripheral nerve entrapment, scar tissue, pelvic nerve irritation, abdominal wall nerve pain, cluneal neuralgia, peroneal nerve entrapment, cubital tunnel syndrome, hernia-related nerve pain, spine-related nerve pain, inflammatory disease, CRPS, or central sensitization.
MPM reviews the pain pattern, nerve territory, physical exam, prior imaging, ultrasound findings, EMG or nerve testing when available, prior nerve block response, medication history, and red flags before recommending hydrodissection or another pathway.
Patients often search for nerve hydrodissection in Manhattan when they have burning, tingling, shooting, electric, radiating, or focal nerve pain that has not improved with standard care. Many have already tried medications, physical therapy, imaging, nerve studies, pelvic floor care, orthopedic care, neurology, injections, or pain management. Some are considering next steps after temporary relief from a nerve block or before peripheral nerve stimulation or neuromodulation.
MPM approaches nerve hydrodissection as a precise, ultrasound-guided technique, not a general treatment for all neuropathic pain. The procedure may be helpful when symptoms and imaging suggest that a peripheral nerve is mechanically irritated, restricted, or compressed by surrounding tissue. It may provide diagnostic information, temporary relief, or both. If the response is meaningful, it can help guide care. If the response is limited, MPM may reassess whether the pain is coming from another nerve, spine condition, pelvic floor dysfunction, hernia-related pathology, inflammatory process, or centralized pain mechanism.
Nerve hydrodissection fits within MPM’s Complex Chronic Pain and Musculoskeletal issues expertise because nerve pain often overlaps with tissue, joint, spine, pelvic, abdominal wall, and post-surgical pain patterns. A patient may have a peripheral nerve entrapment, scar-related nerve pain, cluneal neuralgia, pudendal neuralgia, abdominal wall nerve pain, hernia-related nerve irritation, peroneal nerve entrapment, or a broader complex chronic pain picture.
MPM uses nerve hydrodissection as part of a diagnosis-first framework. It may provide useful information and temporary symptom relief, but it is not a cure for every nerve pain condition. Treatment planning may also include ultrasound-guided injections, peripheral nerve blocks, nerve hydrodissection, peripheral nerve stimulation, neuromodulation, medication management, rehabilitation, pain psychology, pelvic floor care, neurology, or surgical evaluation when appropriate.
Before nerve hydrodissection, MPM reviews the suspected nerve target, pain pattern, ultrasound findings when available, medication history, prior treatment response, risks, alternatives, and post-procedure instructions. During the procedure, ultrasound guidance is used to visualize the target region and guide fluid around the nerve or surrounding tissue plane. The injectate may vary depending on the clinical situation.
Patients may feel pressure, brief discomfort, temporary numbness, warmth, soreness, or a short pain flare after the procedure. Relief may be temporary and may last hours, days, weeks, or longer depending on the nerve, diagnosis, injectate, and pain mechanism. Some patients may not respond. MPM reviews the response to determine whether the nerve target appears clinically meaningful and whether additional nerve-focused care, peripheral nerve stimulation, neuromodulation, rehabilitation, or specialty evaluation should be considered.

The best care I've received as a chronic pain patient. I traveled from out of state to visit Manhattan Pain Medicine because I could not find knowledgeable doctors in my hometown for my hypermobility, and Ehlers-Danlos syndrome symptoms and comorbidities. Let me tell you, it was worth every travel e...
I was injured in a bicycle accident over 8 years ago. I’ve suffered throughout the years since my accident with nothing seeming to work. PT, Yoga, lifestyle changes, NOTHNG! I finally made an appointment with Dr Kane and I’m feeling an improvement in my life. I no longer stay up all night in pain, a...
One of the best experiences, if not the best, I have ever had at the doctor’s office. From the front desk to the nurses to the PA assisting the doctor this was a great experience. Dr.Nino actually listened to me and came up with a game plan. Would recommend this practice to as many people as I could...
I have very unique & severe nerve pain from CRPS which has no known specific cure. Dr. Siefferman has a huge tool box, far greater than the other 23 Drs. I have seen. He saved me from jumping off a bridge and continues to help me with both treatments and advice. Dr. S. is in a different league!
After two years of searching and feeling lost and let down, I finally found real help at Manhattan Pain Medicine. With Dr. Siefferman, Adam Rosenberg, Dr. Mikaberidze, and the whole team, I feel heard, supported and understood. Every symptom is being considered and I’m finally getting answers with m...

The staff was friendly and helpful. Dr. Siefferman was thoughtful, listened, asked questions and proposed simple safe ways to come to further conclusions regarding my pain and discomfort. The office staff including Dr. Siefferman is responsive even after the initial in-person visit. Very pleased.
Dr. Siefferman is a brilliant provider. While my pain is still a work in progress, Dr Siefferman always gives me options and explains his reasoning behind things. He listens to my feedback and concerns. I never feel rushed; and am grateful he works to meet me where I am. I highly recommend him.
What a great find! They listen to me, I listen to them and the diagnosis is made and a plan developed to develop an approach to treat all of my chronic pain. I wish I could have discovered this type of treatment sooner. This doctor and group give me hope.
Nerve hydrodissection is an ultrasound-guided procedure that uses fluid to separate a peripheral nerve from surrounding tissue, fascia, scar tissue, muscle, or other nearby structures when nerve entrapment or mechanical irritation is suspected. It may be considered for selected patients with nerve-like pain such as burning, tingling, shooting, electric, radiating, or focal pain. At MPM, nerve hydrodissection NYC care begins with diagnosis-first evaluation to confirm whether a specific nerve is a reasonable target.
Nerve hydrodissection works by placing fluid around a selected nerve to create space between the nerve and nearby tissue planes. This may reduce mechanical irritation in selected entrapment patterns and may also provide diagnostic information. The fluid or medication used depends on the clinical situation. Nerve hydrodissection is not appropriate for every type of nerve pain, and response varies by diagnosis, anatomy, symptom duration, and the underlying cause of nerve irritation.
Ultrasound-guided nerve hydrodissection means the clinician uses real-time ultrasound imaging to identify the target region and guide the procedure. Ultrasound may help visualize the nerve, surrounding tissue, nearby vessels, and the spread of fluid around the nerve. Ultrasound guidance does not guarantee relief, but it may support more precise treatment planning in selected cases. MPM determines whether hydrodissection is appropriate based on symptoms, anatomy, and clinical findings.
Nerve hydrodissection may be considered for selected peripheral nerve entrapment or irritation patterns, including scar-related nerve pain, cluneal neuralgia, pudendal nerve pain, abdominal wall nerve pain, hernia-related nerve pain, peroneal nerve entrapment, cubital tunnel syndrome, and certain foot or ankle nerve symptoms. It is not a general treatment for all neuropathy or chronic pain. MPM evaluates whether the suspected nerve target matches the patient’s symptoms before recommending treatment.
Nerve hydrodissection may be considered when symptoms and ultrasound findings suggest that a peripheral nerve is restricted, compressed, or irritated by surrounding tissue, fascia, scar tissue, or nearby anatomy. It may help create space around the nerve and may provide temporary relief. It does not cure every nerve entrapment condition, and some cases may require medication management, physical therapy, nerve testing, imaging, peripheral nerve stimulation, neuromodulation, or surgical evaluation.
Nerve hydrodissection may be considered in selected pelvic nerve pain patterns when a peripheral nerve appears mechanically irritated or restricted. Pelvic pain can also come from pelvic floor dysfunction, pudendal neuralgia, pelvic dystonia, PGAD-related sensory symptoms, endometriosis, spine-related pain, abdominal wall pain, hernia-related pain, or central sensitization. MPM evaluates pelvic pain carefully before recommending hydrodissection, pudendal nerve block, pelvic specialty care, peripheral nerve stimulation, or another treatment pathway.
Nerve hydrodissection may be considered for selected pudendal nerve pain patterns when symptoms, exam findings, and imaging suggest possible mechanical nerve irritation. It is not automatically appropriate for every patient with pudendal neuralgia, pelvic floor dysfunction, or PGAD-related symptoms. MPM may consider pudendal nerve block, pelvic floor care, medication management, pain psychology, peripheral nerve stimulation, neuromodulation, gynecology, urology, colorectal care, or neurology coordination depending on the patient’s presentation.
Nerve hydrodissection may be considered for selected abdominal wall or hernia-related nerve pain when symptoms suggest irritation or entrapment of a peripheral nerve. Pain may be related to scar tissue, prior surgery, abdominal wall nerve entrapment, hernia repair, femoral hernia, obturator hernia, sports hernia, or other structural issues. MPM evaluates whether surgical, gastrointestinal, pelvic, or emergency causes should be addressed before recommending a nerve-focused procedure.
Nerve hydrodissection may be considered for selected cluneal nerve pain when symptoms suggest superficial nerve irritation, entrapment, or restriction. Cluneal neuralgia may cause pain around the low back, buttock, iliac crest, or nearby regions and can overlap with sacroiliac joint pain, lumbar spine pain, hip pain, or myofascial pain. MPM maps the pain pattern and may use ultrasound-guided evaluation to determine whether a cluneal nerve target is appropriate.
Nerve hydrodissection may be considered for selected lower-extremity nerve entrapment patterns, including peroneal nerve irritation or certain foot and ankle nerve symptoms. Tarsal tunnel-type pain, burning foot pain, numbness, or tingling can come from nerve entrapment, spine-related nerve pain, neuropathy, vascular disease, joint mechanics, or foot structure. MPM evaluates the suspected nerve territory and may coordinate imaging, EMG or nerve testing, orthopedics, neurology, or podiatry when appropriate.
A nerve block places medication near a nerve to temporarily reduce pain or help confirm a nerve pain source. Nerve hydrodissection uses fluid to separate the nerve from surrounding tissue planes when mechanical irritation or entrapment is suspected. Some procedures may include both diagnostic and therapeutic goals. MPM decides between a nerve block, hydrodissection, or another treatment based on the suspected pain generator, ultrasound findings, prior response, and patient goals.
Nerve hydrodissection is a minimally invasive, ultrasound-guided procedure that uses fluid to create space around a nerve. Surgery may involve direct release, repair, decompression, or revision depending on the condition. Hydrodissection is not a substitute for surgery when structural pathology, severe compression, progressive weakness, vascular compromise, infection, or other surgical issues are present. MPM may recommend surgical evaluation when symptoms, imaging, or neurological findings suggest that it is needed.
Relief varies by diagnosis, nerve target, injectate, symptom duration, and the underlying cause of nerve irritation. Some patients may experience relief for hours or days, while others may notice longer improvement. Some patients may not respond. Relief is often temporary, but it can still be clinically useful if it helps confirm that the targeted nerve is involved. MPM uses the response to guide future treatment planning.
Risks may include pain flare, bruising, bleeding, infection, allergic reaction, temporary numbness or weakness, nerve irritation, vascular injury, local anesthetic toxicity, steroid-related side effects when steroids are used, incomplete relief, temporary relief only, or no relief. MPM reviews these risks before treatment. Fever, spreading redness, severe swelling, new weakness, new numbness, limb discoloration, loss of pulses, severe allergic reaction, or rapidly worsening symptoms require urgent evaluation.
Nerve hydrodissection may not be appropriate when symptoms do not suggest a specific peripheral nerve target, when the main cause is spine-related, vascular, infectious, inflammatory, surgical, or centrally mediated, or when urgent evaluation is needed. It is not a replacement for diagnosis, medication management, physical therapy, pelvic specialty care, neurology, EMG or nerve testing, imaging, surgery, peripheral nerve stimulation, neuromodulation, or emergency care when those are needed.
Before care begins, our team helps patients understand the practical side of treatment, including insurance verification, out-of-network benefits, cost-share estimates, self-pay options, and billing questions. We believe patients should have as much clarity as possible before moving forward.
If you are considering nerve hydrodissection in NYC for suspected nerve entrapment, scar-related nerve pain, pelvic nerve pain, cluneal neuralgia, abdominal wall pain, hernia-related nerve pain, peroneal nerve entrapment, or complex nerve pain, MPM can help determine whether this treatment may be appropriate. Your evaluation will consider your symptoms, anatomy, ultrasound findings when relevant, prior care, safety factors, and care goals before any recommendation is made.
Nerve hydrodissection is an ultrasound-guided procedure that uses fluid to separate a peripheral nerve from surrounding tissue, fascia, scar tissue, muscle, ligament, or other nearby structures when nerve entrapment or mechanical irritation is suspected. The goal is to create space around the nerve and reduce tissue restriction in selected cases.
At Manhattan Pain Medicine (MPM), nerve hydrodissection NYC care begins with diagnosis-first evaluation. The goal is to determine whether a specific peripheral nerve appears to be involved, whether hydrodissection is appropriate, and how the response may guide the broader care plan.
During nerve hydrodissection, ultrasound is used to visualize the target region and guide fluid around the nerve or surrounding tissue plane. The injectate may vary depending on the clinical situation and may include local anesthetic, saline, dextrose solution, or other medication when clinically appropriate.
This is different from a standard nerve block. A nerve block primarily places medication near a nerve to temporarily interrupt pain signaling or help confirm the pain source. Hydrodissection focuses on mechanically separating the nerve from surrounding tissue planes when entrapment, scar restriction, or mechanical irritation is suspected.
Nerve hydrodissection may be considered for selected peripheral nerve entrapment or irritation patterns. These may include scar-related nerve pain, cluneal neuralgia, abdominal wall nerve pain, hernia-related nerve pain, pelvic nerve pain, pudendal nerve irritation, peroneal nerve entrapment, cubital tunnel syndrome, and certain foot or ankle nerve symptoms.
It may also be considered after a diagnostic nerve block provides temporary relief and suggests a meaningful nerve target. However, hydrodissection is not appropriate for every patient with neuropathy, nerve pain, pelvic pain, abdominal pain, foot pain, or complex chronic pain.
Nerve-like pain can feel burning, tingling, shooting, electric, stabbing, radiating, or numb. These symptoms may suggest nerve involvement, but they do not automatically identify the source. Similar symptoms can come from spine-related nerve pain, peripheral neuropathy, vascular disease, CRPS, inflammatory conditions, pelvic floor dysfunction, joint mechanics, scar tissue, hernia-related pathology, or central sensitization.
MPM evaluates the full clinical picture before recommending hydrodissection. This may include symptom mapping, physical exam, ultrasound evaluation, imaging review, medication review, prior injection response, EMG or nerve testing when available, and coordination with other specialists when appropriate.
MPM’s experience with complex pain allows nerve hydrodissection to be considered in selected pelvic, abdominal wall, and hernia-related nerve pain patterns. These cases require careful evaluation because pain may come from nerves, fascia, pelvic floor dysfunction, prior surgery, abdominal wall structures, hernia repair, spine conditions, or visceral sources.
For pelvic pain, MPM may consider whether symptoms suggest pudendal neuralgia, pelvic floor dysfunction, pelvic dystonia, PGAD-related sensory symptoms, cluneal nerve involvement, or another peripheral nerve pattern. For abdominal or hernia-related pain, MPM considers whether surgical evaluation, gastrointestinal evaluation, or imaging should occur before a nerve procedure.
The response to nerve hydrodissection can help guide future care. If relief is meaningful, it may support the nerve target as clinically relevant. Next steps may include rehabilitation, medication management, repeat evaluation, nerve hydrodissection in selected cases, peripheral nerve stimulation, neuromodulation, or specialist coordination.
If relief is limited or absent, the pain is still real. It may mean that the target was not the primary pain generator, the diagnosis needs refinement, or another mechanism is contributing. MPM may then consider a different nerve target, spine evaluation, pelvic specialty care, surgery referral, neurology evaluation, medication management, or a broader complex pain plan.
Risks may include pain flare, bruising, bleeding, infection, allergic reaction, temporary numbness or weakness, nerve irritation, vascular injury, local anesthetic toxicity, steroid-related side effects when steroids are used, incomplete relief, temporary relief only, or no relief.
Patients should seek urgent evaluation for fever, spreading redness, severe swelling, new weakness, new numbness, rapidly worsening pain, bowel or bladder dysfunction, saddle anesthesia, chest pain, shortness of breath, sudden severe headache, severe abdominal or pelvic pain, loss of pulses, limb discoloration, suspected infection, severe allergic reaction, or rapidly worsening symptoms.
For selected patients, nerve hydrodissection may be an important step in understanding and managing peripheral nerve pain. MPM’s role is to determine whether the nerve target is clinically appropriate and how hydrodissection fits within a coordinated, medically responsible care plan.
