Neuropathy in feet is nerve damage that causes burning, tingling, numbness, or shooting pain in the toes and soles. The most common cause is high blood sugar from diabetes or prediabetes, which slowly injures the small nerves that supply the feet. Early diagnosis and treatment can slow the damage and prevent serious complications such as foot ulcers.
What Is Peripheral Neuropathy in the Feet?
Peripheral neuropathy is damage to the peripheral nerves — the nerves outside the brain and spinal cord. When these nerves are injured in the feet, signals between the foot and the brain become distorted or lost. This is called distal symmetric polyneuropathy when it affects both feet equally, which is the typical pattern in diabetes.
Three types of nerves can be affected:
- Sensory nerves — control how you feel temperature, pain, and vibration.
- Motor nerves — control muscle movement, including the small muscles in the foot arch.
- Autonomic nerves — control sweating and blood flow regulation in the foot.
What Causes Neuropathy in the Feet?
Diabetes is by far the leading cause in the United States. According to the CDC, about half of people with diabetes will develop some form of peripheral neuropathy. But other conditions can also damage the nerves in your feet.
Diabetes and Prediabetes
Chronically high blood glucose injures small blood vessels (vasa nervorum) that feed the nerves, and it triggers inflammation and oxidative stress that directly damage nerve fibers. This nerve damage can start during prediabetes — before A1C crosses into the diabetic range. If you have not yet been tested, see our guide to A1C levels.
Other Common Causes
- Heavy alcohol use
- Vitamin B12, B1, B6, or vitamin E deficiency
- Chemotherapy (especially platinum and taxane drugs)
- Autoimmune disease (lupus, rheumatoid arthritis, Sjögren’s)
- Hypothyroidism
- Chronic kidney disease
- HIV, Lyme disease, hepatitis C, shingles
- Spinal nerve compression
- Heavy metal or industrial chemical exposure
- Inherited conditions such as Charcot-Marie-Tooth disease
Symptoms of Neuropathy in Feet
Symptoms usually begin in the toes and progress slowly upward in a “stocking” pattern. Both feet are typically affected. Many people first notice symptoms at night, when there are fewer distractions.
| Stage | Common Symptoms |
|---|---|
| Early | Tingling, pins and needles, mild burning in toes |
| Moderate | Sharp shooting pains, increased burning, sensitivity to bedsheets, loss of vibration sense |
| Advanced | Numbness, loss of pain and temperature sensation, balance problems, foot deformity, ulcers |

How Neuropathy in Feet Is Diagnosed
Diagnosis starts with a thorough history and a focused foot exam. Your clinician will ask when symptoms began, what makes them better or worse, and whether you have other risk factors such as diabetes or alcohol use.
In-Office Tests
- 10-gram monofilament test — a thin nylon filament is pressed against several spots on the sole. If you cannot feel it, you have lost protective sensation.
- Tuning-fork vibration test — a 128 Hz tuning fork is held against the big toe. Reduced vibration sensing is an early sign of large-fiber neuropathy.
- Pinprick and temperature testing — checks small-fiber function.
- Ankle reflex testing — diminished reflexes suggest motor nerve involvement.
Specialist Tests
- Nerve conduction studies (NCS) and electromyography (EMG) — measure how fast and how well nerves transmit signals.
- Skin biopsy — counts the small nerve fibers in a tiny piece of skin to confirm small-fiber neuropathy.
- Blood work — A1C, vitamin B12, thyroid panel, kidney function, and a metabolic panel to find treatable causes.
Treatment Options for Neuropathy in Feet
Treatment has two parallel goals: address the underlying cause and relieve the symptoms.
1. Treat the Underlying Cause
If diabetes is the cause, intensive blood sugar control is the single most important step. The American Diabetes Association reports that tight glycemic control can dramatically reduce the risk of new neuropathy in type 1 diabetes and modestly reduce risk in type 2. For prediabetes, see our guide on whether prediabetes is reversible through diet and weight loss.
Other underlying causes — vitamin deficiency, alcohol use, hypothyroidism — should be corrected directly.
2. Medications for Symptom Relief
| Medication | Class | Common Use |
|---|---|---|
| Pregabalin (Lyrica) | Anticonvulsant | FDA-approved for diabetic neuropathy pain |
| Gabapentin (Neurontin) | Anticonvulsant | Off-label, widely used first-line |
| Duloxetine (Cymbalta) | SNRI antidepressant | FDA-approved for diabetic neuropathy |
| Amitriptyline / nortriptyline | Tricyclic antidepressant | Off-label, low-dose for nerve pain |
| Tapentadol ER | Opioid analog | FDA-approved when other options fail |
| Lidocaine 5% patch | Topical anesthetic | Localized burning pain |
| Capsaicin 8% patch | Topical | Reduces substance P; in-office application |
All medications carry side effects. Your doctor will choose based on your kidney function, mood, sleep, weight, and other medications.
3. Supplements With Evidence
- Alpha-lipoic acid (ALA) — an antioxidant studied at 600 mg daily; multiple trials show modest improvement in burning and tingling.
- Acetyl-L-carnitine — may improve nerve function and pain in diabetic neuropathy.
- Vitamin B12 — essential if you are deficient, especially if you take metformin long-term.
- Benfotiamine — a fat-soluble form of B1 with some supportive evidence.
Discuss supplements with your doctor before starting.
4. Physical Therapy and Movement
A physical therapist can teach balance exercises (important because numb feet raise fall risk), gait retraining, and stretching to prevent foot deformity. Aerobic exercise — even walking — improves blood flow to the nerves and may reduce pain.
5. Other Therapies
- Transcutaneous electrical nerve stimulation (TENS)
- Acupuncture (mixed but generally favorable evidence)
- Cognitive behavioral therapy for chronic pain
- Properly fitted shoes and custom orthotics
Daily Foot Care to Prevent Complications
When sensation is reduced, a small cut or blister can become a serious foot ulcer without you noticing. The CDC recommends a daily foot-care routine:
- Inspect the tops, soles, and between toes every day — use a mirror or ask for help.
- Wash with lukewarm (not hot) water; dry thoroughly, especially between toes.
- Moisturize the tops and soles, but not between the toes.
- Trim toenails straight across; have a podiatrist do it if you cannot see well.
- Never go barefoot, even indoors.
- Check shoes for pebbles, rough seams, or torn linings before putting them on.
- Get an annual comprehensive foot exam — more often if you already have neuropathy.
How to Prevent Neuropathy in Feet
If you have prediabetes or diabetes, prevention is the same as treatment of the underlying cause:
- Aim for an A1C target set with your doctor (often under 7.0% for diabetes; under 5.7% for prediabetes prevention).
- Lose 5 to 7 percent of body weight if you are overweight.
- Get at least 150 minutes per week of moderate aerobic activity.
- Follow a Mediterranean or low-glycemic eating pattern — see our diet and nutrition hub.
- Limit alcohol to no more than one drink a day.
- Don’t smoke — tobacco constricts blood vessels and worsens nerve damage.
- Keep blood pressure and LDL cholesterol in target range.
When to See a Doctor
Make an appointment if you have:
- Persistent tingling, burning, or numbness in your feet
- A cut, blister, or callus that isn’t healing
- Sudden, severe weakness in a foot or leg
- A foot deformity such as a hammertoe or arch collapse
- Loss of balance or frequent falls
Seek urgent care for any open wound on a numb foot — these can become infected quickly.
The Bottom Line
Neuropathy in the feet is most often a complication of diabetes or prediabetes, and it can develop silently before sensation is fully lost. The combination of strict blood-sugar control, evidence-based medications, supplements such as alpha-lipoic acid, physical therapy, and daily foot inspection can relieve symptoms and prevent ulcers and amputation. If your feet are tingling, burning, or feeling numb — don’t wait. Get tested, get treated, and protect the feet you walk on.
