Peripheral neuropathy — the burning, tingling, numbness, or shooting pain of damaged nerves — is one of the conditions Frequency Specific Microcurrent is most often used for at home. FSM uses paired frequencies: one chosen to resonate with nerve tissue and another to reduce inflammation or address the underlying cause, delivered together through gentle microcurrent.

In the video below, Dr. Mittag demonstrates how to use an FSM unit for peripheral neuropathy pain, including pad placement and how the prescribed protocols are run. Because FSM devices require a prescription, each unit is programmed for the individual after Dr. Mittag reviews their health history and symptoms in a consultation.

If you think FSM might help your condition, the first step is a short consultation with Dr. Mittag to see whether FSM is right for you.

What Is Peripheral Neuropathy?

Peripheral neuropathy simply means damage, disease, or dysfunction of nerves outside the brain and spinal cord. These include the nerves that power your muscles, carry sensations like touch and pain, and even regulate internal organs through the autonomic nervous system.

When these nerves are injured or not working properly, symptoms can vary widely. Some people experience numbness, tingling, or “pins and needles.” Others feel burning or stabbing pain, or even pain from something as light as clothing brushing against the skin. Muscles can weaken or twitch, and internal organ function can be affected too.

What Causes Peripheral Neuropathy?

There isn’t just one cause — in fact, neuropathy can result from many different issues. Among the most common are:

  • Diabetes and pre-diabetes (one of the leading causes)

  • Medications, especially statin drugs

  • Toxins, such as pesticides or heavy metals like mercury and lead

  • Mechanical pressure, like a herniated disc pressing on a nerve

  • Nutritional deficiencies, particularly B12, folate, Omega-3 fatty acids, and CoQ10

  • Autoimmune conditions, such as non-celiac gluten sensitivity

  • Chronic infections, including Lyme disease, Epstein-Barr, and others

Often, more than one factor can be at play. For example, someone might have both diabetes and toxin exposure, each damaging the same nerve.

How FSM Helps

FSM works by delivering gentle, low-level electrical currents at precise frequencies designed to reduce pain, calm inflammation, and restore nerve function. What makes it powerful is that it doesn’t just mask symptoms — it supports the body’s own healing process.

There are FSM protocols specifically designed for:

  • Nerve pain relief

  • Clearing toxins from nerves

  • Addressing infections in nerves

  • Restoring nerve function

  • Softening scar tissue that tugs on nerves

But FSM doesn’t stop there. The therapy can also be tailored to target the root causes of neuropathy. For example:

  • If neuropathy is linked to diabetes, FSM can support insulin resistance and liver health alongside direct nerve treatment.

  • If a statin drug is suspected, FSM can help the liver and kidneys clear toxins, while the patient works with their doctor on adjusting medications.

  • If gluten sensitivity is involved, FSM may reduce nerve pain while the patient removes gluten from their diet to stop the immune attack on their nerves.

What Research Shows

In a clinical study entitled "Nonpharmacologic Treatment of Neuropathic Pain Using Frequency Specific Microcurrent" Dr. Carolyn McMakin details the results of 20 peripheral neuropathy patients after being treated with FSM.

Of the 20 patients treated, 65% fully recovered from nerve pain.  25% terminated care for unknown reasons.  One patient was referred for additional treatment via a steroid injection.  Another patient was given an FSM unit for self treatment at home and also recovered after the study.

Real-Life Examples

One powerful story that comes from a patient shows how dramatically FSM can help neuropathy. This was a client of mine who presented with acute neuropathy due to a shingles (varicella-zoster virus) infection. Despite strong antiviral and pain medications, she was still at a 10 out of 10 on the pain scale. After just three hours of FSM using the shingles protocol, her pain dropped to a four. The next day, after another treatment, it fell to a two — and within a week, it was gone.

Another example involves gluten-triggered neuropathy. A patient with small fiber neuropathy found their pain nearly disappeared after strictly avoiding gluten. But just a few holiday indulgences brought the pain roaring back — proof that removing the trigger was as important as treating the nerve.

In Summary

FSM provides a safe, drug-free way to relieve peripheral neuropathy pain while also helping uncover and address its root causes. Whether your neuropathy comes from diabetes, toxins, infections, autoimmunity, or even scar tissue, FSM offers tools to both calm the symptoms and support true healing.

It’s important to remember: nerves can heal, but only if the causes of damage are identified and removed. FSM can help ease the pain while guiding your body back toward balance.

So if you’re struggling with neuropathy, don’t lose hope. With the right approach — combining FSM therapy with lifestyle changes and medical guidance — relief and recovery may be closer than you think.
