Living with Neuropathy: More Than Just Numbness
Peripheral neuropathy affects an estimated 20 million Americans, causing symptoms that range from mild tingling to debilitating pain and loss of function. For many, it starts subtly—a little numbness in the toes, occasional burning sensations—but progressively worsens over time.
The most common cause is diabetes, but neuropathy can also result from chemotherapy, autoimmune conditions, injuries, infections, or sometimes has no identifiable cause (idiopathic neuropathy). Regardless of the cause, the underlying problem is the same: damaged or dysfunctional peripheral nerves that can't properly transmit signals between your brain and extremities.
Traditional treatments focus on managing symptoms—pain medications, antidepressants, anticonvulsants—but these don't address the nerve damage itself. Many patients find themselves on an escalating regimen of medications with diminishing returns and increasing side effects.
Sound familiar?
- Numbness or reduced sensation in hands or feet
- Burning, tingling, or 'pins and needles' sensations
- Sharp, stabbing, or electric shock-like pain
- Extreme sensitivity to touch
- Muscle weakness or coordination problems
- Balance issues, especially in the dark
- Foot ulcers or infections that won't heal (diabetic neuropathy)
How Shockwave Therapy Promotes Nerve Healing
Extracorporeal shockwave therapy (ESWT) uses acoustic pressure waves to trigger biological responses that support nerve regeneration. Unlike medications that mask symptoms, shockwave therapy targets the underlying nerve dysfunction through multiple mechanisms.
Shockwave therapy promotes axonal regrowth and myelination—the regeneration of nerve fibers and their protective coating. Research shows ESWT influences Schwann cells, which are essential for peripheral nerve repair and regeneration.
ESWT significantly reduces inflammatory markers like IL-1β and IL-6 in damaged nerve tissue. Chronic inflammation is a major contributor to ongoing nerve damage and pain, so reducing it helps create conditions for healing.
Shockwaves stimulate neovascularization—the formation of new blood vessels. Better blood supply to peripheral nerves means improved oxygen and nutrient delivery, essential for nerve health and regeneration.
ESWT activates cellular repair mechanisms, including improved mitochondrial function and growth factor release. This creates a regenerative environment that supports nerve tissue healing.

What the Research Shows
While shockwave therapy for neuropathy is an emerging field, clinical evidence is growing. Here's what current research demonstrates:
ESWT for Nerve Injury and Scarring (Double-Blind RCT)
In a rigorous double-blind, randomized controlled trial with 103 patients, ESWT significantly improved hand function in patients with nerve injuries. The treatment group showed better pain scores, joint mobility, and fine motor function compared to sham treatment.
ESWT and Nerve Regeneration Mechanisms
Animal research demonstrates that ESWT promotes nerve regeneration through multiple pathways: reducing inflammation (IL-1β, IL-6), protecting neurons (NeuN expression), and improving mitochondrial function. Multiple treatment sessions showed superior outcomes.
ESWT for Diabetic Foot Microcirculation
Studies on diabetic patients show that ESWT improves microcirculation in affected tissues, which is crucial for both wound healing and nerve health in diabetic neuropathy.
Mechanotransduction and Schwann Cells
Research shows ESWT's mechanical stimulation affects Schwann cell differentiation and myelin gene regulation—key processes in peripheral nerve regeneration. This mechanotransductive effect may accelerate nerve healing.
Shockwave Therapy vs Other Neuropathy Treatments
Understanding how ESWT compares to other options helps you make an informed decision about adding it to your treatment plan.
Medications (Gabapentin, Pregabalin, Duloxetine)
Pros
- FDA-approved for neuropathic pain

- May require dose escalation over time
- Dependency concerns with some medications
- May interact with other medications
Topical Treatments (Capsaicin, Lidocaine)
Pros
- Minimal systemic side effects
- Can be used alongside other treatments
- Available over-the-counter
Cons
- Temporary relief only
- May cause local skin irritation
- Effectiveness varies widely
- Don't address nerve damage
Physical Therapy
Pros
- Improves strength and balance
- No medication side effects
- Addresses functional limitations
- Often covered by insurance
Cons
- Time-intensive commitment
- Doesn't directly treat nerve damage
- Benefits depend on patient compliance
- May be limited for severe cases
Why Choose Shockwave Therapy?
What to Expect During Treatment
Initial Assessment
We evaluate your neuropathy symptoms, underlying causes, current treatments, and goals. This helps us determine if shockwave therapy is appropriate and create a personalized protocol.
Treatment Sessions
You'll be positioned comfortably while the clinician applies the shockwave applicator to the affected areas—typically the feet, ankles, and lower legs for peripheral neuropathy. Most patients describe the sensation as a gentle tapping or pulsing.
Recovery
There's no downtime—you can resume normal activities immediately. Some patients notice mild warmth or tingling in treated areas that resolves quickly.
Results Timeline
Nerve regeneration takes time. Some patients notice reduced pain or improved sensation within a few weeks, but optimal results typically develop over 2-3 months as nerve tissue heals and regenerates.
Is Shockwave Therapy Right for Your Neuropathy?
Ideal Candidates
- Patients with diabetic peripheral neuropathy
- Those experiencing medication side effects or seeking alternatives
- Patients with idiopathic (unknown cause) neuropathy
- Those with neuropathy from chemotherapy (after completing treatment)
- Patients with localized nerve injuries or compression
- Those who want to complement existing treatments
- Patients seeking non-invasive options before considering surgery
May Need Alternatives
- • Patients with active infections in treatment areas
- • Those with bleeding disorders or on blood thinners (requires evaluation)
- • Patients with implanted devices in treatment areas
- • Those with rapidly progressive neurological conditions
- • Patients whose neuropathy requires urgent surgical intervention
Frequently Asked Questions
Can shockwave therapy cure my neuropathy?
Shockwave therapy promotes nerve regeneration and may improve symptoms, but results vary depending on the type and severity of neuropathy, how long you've had it, and underlying causes. It's best viewed as a treatment that can support nerve healing rather than a guaranteed cure. Many patients experience meaningful improvement in pain, sensation, and function.
How is this different from TENS units or electrical stimulation?
TENS units deliver small electrical currents that temporarily interrupt pain signals—providing relief but not addressing nerve damage. Shockwave therapy uses acoustic pressure waves that trigger biological responses: nerve regeneration, reduced inflammation, and improved blood flow. It's targeting the underlying condition rather than just masking symptoms.
Is the treatment painful?
Most patients describe the sensation as mild tapping or pulsing. Areas with more severe neuropathy may be slightly more sensitive, but the intensity is adjustable. Many patients actually find the treatment comfortable. No anesthesia is needed.
Can I continue my current neuropathy medications?
Yes, shockwave therapy can be used alongside your current medications. We don't recommend stopping any prescribed medications without consulting your doctor. Some patients find they can reduce their medication over time as symptoms improve, but this should be done under medical supervision.
How long do the results last?
Because shockwave therapy promotes actual nerve regeneration rather than just symptom relief, improvements can be long-lasting. However, if the underlying cause (like uncontrolled diabetes) continues to damage nerves, symptoms may return. Managing root causes alongside shockwave treatment produces the best long-term outcomes.
How many sessions will I need?
A typical treatment protocol involves 6-12 sessions over several weeks. The exact number depends on the severity of your neuropathy and your response to treatment. We reassess regularly and adjust the protocol based on your progress.
Is shockwave therapy covered by insurance for neuropathy?
Currently, most insurance plans don't cover shockwave therapy for neuropathy. We offer financing options to make treatment accessible. Consider that reducing medication costs and improving function may offset the treatment investment over time.
