Peripheral neuropathy can be managed through a combination of treating the underlying cause, reducing pain with medications or topical treatments, and protecting your body from further nerve damage. There is no single cure, but most people find meaningful relief by layering several approaches together. The right strategy depends on what’s causing your neuropathy, which nerves are affected, and how severe your symptoms are.
Finding the Cause Comes First
Before jumping to pain relief, identifying why your nerves are damaged changes everything about treatment. Diabetes is the most common cause, but neuropathy can also stem from vitamin deficiencies, alcohol use, autoimmune conditions, infections, kidney disease, and certain medications (especially some chemotherapy drugs). In roughly a quarter of cases, no clear cause is found.
Doctors typically use two tests together to confirm nerve damage and pinpoint its severity. A nerve conduction study measures how fast and how strongly electrical signals travel through your nerves. A damaged nerve produces a slower, weaker signal. An electromyography (EMG) test checks the electrical activity in your muscles at rest and during movement. Healthy muscles produce no electrical signals when you’re still, so abnormal activity at rest points to nerve-related damage. Together, these tests help distinguish nerve problems from muscle problems and guide the treatment plan.
Blood work is also standard. One critical test checks your vitamin B12 level. The conventional cutoff for B12 deficiency ranges from 150 to 220 pmol/L, and falling below that range can directly cause nerve damage that is often reversible with supplementation. Blood sugar and A1c testing rules out diabetes as the driver.
Treating the Root Cause
When neuropathy has an identifiable cause, treating that cause is the single most effective step. For diabetic neuropathy, which accounts for the largest share of cases, tight blood sugar control slows progression and can partially reverse early damage. The American Diabetes Association recommends most adults aim for an A1c below 7.0%, though your target may be adjusted based on your age and overall health.
If B12 deficiency is the problem, replenishment can begin reversing symptoms within weeks. Adults with normal absorption typically take 1,000 mcg orally once per day. People with impaired absorption, such as those with pernicious anemia, often need injections: 1,000 mcg weekly for the first four weeks, then monthly. When neurological symptoms are already present, treatment usually starts more aggressively with injections every other day for about two weeks before shifting to monthly maintenance. The earlier you catch B12-related neuropathy, the more nerve function you can recover.
For neuropathy caused by alcohol, stopping drinking and correcting the nutritional deficiencies that often accompany heavy use can halt further damage. Medication-induced neuropathy sometimes improves after switching to a different drug, though recovery can take months.
Medications for Nerve Pain
When the burning, tingling, or stabbing pain of neuropathy needs direct treatment, doctors typically choose from a few well-studied medication classes. The American Academy of Neurology’s most recent guidelines (reaffirmed in early 2025) emphasize thinking in terms of medication class: if one drug in a class doesn’t work or causes intolerable side effects, switching to an entirely different class is more effective than trying another drug from the same group.
The two main classes are anticonvulsants (originally developed for seizures but effective for nerve pain) and certain antidepressants that increase the activity of serotonin and norepinephrine in the brain. These chemical messengers play a role in how your body processes pain signals. For diabetic neuropathy specifically, the standard dose of duloxetine is 60 mg once daily. Gabapentin and pregabalin, the most commonly prescribed anticonvulsants for neuropathy, work by calming overactive nerve signals. Your doctor will usually start at a low dose and increase gradually to minimize side effects like drowsiness and dizziness.
One point the guidelines make clearly: opioids should not be used for painful diabetic neuropathy. The risks of dependence and other side effects outweigh the benefits, especially since neuropathy requires long-term management rather than short-term pain control.
Topical Treatments
For people who want to avoid or supplement oral medications, topical options can help, particularly when pain is concentrated in a specific area like the feet. Capsaicin, the compound that makes chili peppers hot, works by overwhelming and then desensitizing pain receptors in the skin. Patches are available in several concentrations, and studies have tested formulations ranging from 0.625% to 1.25%. Over-the-counter creams at lower concentrations (typically 0.075%) are widely available and applied multiple times daily, though they require consistent use over several weeks before pain relief kicks in. The initial burning sensation is common and fades with repeated application.
Lidocaine patches numb the area directly and can provide localized relief without systemic side effects. A 5% lidocaine patch is the most commonly referenced strength in clinical settings. These are particularly useful for people who can’t tolerate oral medications or who have pain limited to a well-defined area.
Supplements That Have Evidence
Alpha-lipoic acid is the supplement with the strongest research backing for diabetic neuropathy. It acts as an antioxidant that may protect nerve cells from further damage. Clinical trials have used 1,800 mg daily (split into three doses) for an initial four-week period, then reduced to 600 mg once daily for ongoing maintenance. Study participants who responded well saw meaningful drops in symptoms like burning, stabbing pain, and numbness. Alpha-lipoic acid is available over the counter, though the quality and dosing of supplements can vary.
B-complex vitamins beyond B12, particularly B1 (thiamine) and B6, also play roles in nerve health. However, too much B6 can actually cause neuropathy, so supplementing without confirmed deficiency is not a good idea.
Physical Therapy and Fall Prevention
Neuropathy in the feet changes more than just sensation. It alters your balance, your gait, and your awareness of where your body is in space. Falls are a serious and underappreciated risk. Altered sensation in the feet is one of the key factors that destabilize balance in older adults, alongside vision changes and inner ear problems.
Exercises that focus on balance and leg strength meaningfully reduce fall risk. A simple but effective routine includes sit-to-stand exercises, which build the leg strength and body mechanics needed to catch yourself, and progressive balance exercises like single-leg stands or tandem walking (placing one foot directly in front of the other). These don’t require a gym. A physical therapist can design a program tailored to your level of sensation loss and overall fitness, which is especially valuable early on when you’re still learning how your body compensates for reduced feeling.
Regular foot inspections matter too. When you can’t feel cuts, blisters, or pressure sores, small injuries can escalate quickly, particularly if you have diabetes. Checking your feet daily and wearing well-fitted, supportive shoes is a simple habit that prevents serious complications.
TENS Units and Other Non-Drug Options
Transcutaneous electrical nerve stimulation (TENS) uses a small, battery-powered device to deliver mild electrical pulses through pads placed on the skin. The pulses are thought to interrupt pain signals traveling to the brain and may trigger the release of natural pain-relieving chemicals. You can adjust the intensity, frequency, and pulse duration until the sensation feels strong but comfortable. Many people use a TENS unit several times a day for up to 60 minutes per session.
TENS units are available without a prescription and have very few side effects, making them a low-risk option to try alongside other treatments. They work best for localized pain and tend to provide temporary relief that lasts during and shortly after use rather than producing lasting changes.
Acupuncture is another option some people explore, with mixed but generally favorable evidence for neuropathic pain. Warm water therapy and regular aerobic exercise (even walking) can also improve circulation to damaged nerves and reduce pain perception over time.
Spinal Cord Stimulation for Severe Cases
When medications, physical therapy, and other conservative approaches haven’t provided enough relief, spinal cord stimulation is an option for refractory cases. A small device is implanted near the spine and sends electrical pulses that interrupt pain signals before they reach the brain. Most people experience about half as much pain after implantation. Before committing to surgery, you go through a trial period with a temporary device. A successful trial typically means at least a 50% reduction in pain.
This is reserved for people who have genuinely exhausted other options. Doctors will usually recommend trying physical therapy, medications from multiple classes, and other nonsurgical treatments first. It’s also considered when taking certain medications like opioids would be unsafe.
Building a Layered Approach
The most effective neuropathy management rarely comes from a single treatment. A typical approach might combine blood sugar control with an oral medication for pain, a topical treatment for breakthrough discomfort, a daily balance exercise routine, and regular foot checks. The AAN guidelines specifically recommend that clinicians review all available options, including oral, topical, and non-drug interventions, rather than relying on any one strategy alone.
Neuropathy often responds slowly to treatment. Nerve regeneration, when it happens, proceeds at roughly an inch per month. Patience with a consistent, multi-pronged plan gives you the best chance of meaningful improvement over the weeks and months ahead.
