Burning, Tingling, or Numb Feet: What Could Be Causing It?

Burning, tingling, or numbness in the feet is often caused by nerve irritation or damage (neuropathy). The most common cause is diabetes-related peripheral neuropathy, but other factors (including vitamin deficiencies, nerve compression, alcohol use, and certain medications) can also be responsible. A thorough assessment is important because treatment depends on the underlying cause.

See a healthcare provider promptly if:

• The numbness or tingling appeared suddenly (within hours) and is progressing
• You have lost the ability to feel hot, cold, or sharp objects on your foot
• The symptoms are accompanied by weakness in the foot or leg
• You notice a wound or sore on a numb area of the foot
• Symptoms began after a back injury or are accompanied by bowel or bladder changes (this could indicate a spinal emergency)

Sudden, progressive neurological symptoms always warrant urgent medical attention.

Diabetic Peripheral Neuropathy The most common cause worldwide. Prolonged high blood sugar damages the small nerves in the feet, typically starting at the toes and progressing upward in a "stocking" pattern. Learn more on our diabetic foot care page.

Vitamin Deficiencies Low levels of vitamin B12, folate, or vitamin D can contribute to neuropathic symptoms. This is worth investigating if you follow a restricted diet or have absorption issues.

Nerve Compression Tarsal tunnel syndrome (compression of the tibial nerve at the ankle) or Morton's neuroma (a thickening of tissue around a nerve between the toes) can cause localised burning, tingling, or numbness.

Alcohol-Related Neuropathy Chronic alcohol use can damage peripheral nerves and deplete B vitamins, contributing to burning or tingling in the feet.

Medication Side Effects Certain medications (including some chemotherapy drugs, statins, and antibiotics) can cause peripheral neuropathy as a side effect.

Other Causes Hypothyroidism, kidney disease, autoimmune conditions, and prolonged pressure on the nerves (from tight footwear or prolonged sitting) can also contribute.

A chiropodist can perform a neurological screening of the feet, including:

• Monofilament testing to assess light-touch sensation
• Vibration testing with a tuning fork
• Reflex assessment
• Vascular check (pulses, capillary refill) to assess circulation

If neuropathy is present, the chiropodist can:

• Provide ongoing foot monitoring and protective care to prevent injuries
• Manage related conditions like calluses, nail changes, and skin breakdown
• Recommend custom orthotics to redistribute pressure and reduce injury risk
• Coordinate with your family doctor or specialist for underlying cause management

For nerve compression conditions, the chiropodist may recommend footwear changes, padding, or orthotics to relieve pressure on the affected nerve.

If sensation in your feet is reduced:

• Inspect your feet daily for cuts, blisters, or redness
• Test bath water temperature with your hand or elbow before stepping in
• Never use heating pads or hot water bottles on your feet
• Wear well-fitting shoes at all times: never walk barefoot
• Have nails trimmed by a professional if you have difficulty seeing or feeling your feet
• Book regular chiropody assessments to catch problems early
