Why are my feet burning or numb if I have diabetes?

Clinical content reviewed by Dr. Fowad Shahzad on 4 November 2026. This guide is educational and does not replace an individual assessment.

Burning, tingling, electric-shock pain or reduced feeling in the feet can occur with diabetes-related nerve damage. Diabetes is not the only possible cause, however. A useful assessment looks at the pattern of symptoms, glucose history, medicines, vitamin deficiencies, thyroid and kidney health, circulation, footwear and the condition of the skin—not the HbA1c result alone.

What can diabetic peripheral neuropathy feel like?

Diabetic peripheral neuropathy commonly begins in the toes or feet and may gradually move upwards. Symptoms can include:

• burning, tingling, pins and needles or electric-shock sensations;
• pain from light touch, such as a bedsheet touching the feet;
• numbness or reduced ability to feel heat, cold, pressure or injury;
• unsteadiness, especially in dim light;
• dry or cracked skin, callus, or changes in the shape of the foot; and
• a wound, blister or shoe injury that was not painful enough to notice early.

Symptoms are often worse at night, but that pattern does not prove the cause. Restless legs, trapped nerves, spinal disease, vitamin deficiencies and circulation problems can produce different or overlapping symptoms.

Does a good HbA1c rule out nerve damage?

No. HbA1c estimates average glucose exposure over the preceding months; it does not directly measure nerve function. Someone may have neuropathy related to earlier glucose exposure, glucose variability, another condition, or more than one cause.

Improving glucose management can reduce the risk of complications and may slow progression, particularly when combined with attention to blood pressure, cholesterol, weight, smoking and other health risks. It should not be presented as a guarantee that established nerve damage will reverse.

If you already have a result, read What does my HbA1c result mean? and bring the actual report and your glucose record to the consultation.

What else can cause burning or numb feet?

A clinician may consider other explanations before attributing every symptom to diabetes. Depending on the history, these may include:

• vitamin B12 deficiency, including in some people who use metformin for a long time;
• hypothyroidism;
• chronic kidney disease;
• alcohol-related or medicine-related nerve injury;
• nerve compression, lumbar spine disease or radiculopathy;
• poor arterial circulation;
• nutritional deficiency after gastrointestinal or metabolic surgery;
• inflammatory, infectious or inherited neuropathies; and
• local skin, joint or footwear problems.

The tests that are useful depend on the individual. A broad laboratory panel is not automatically needed for every patient, and normal blood tests do not replace a focused neurological and foot examination.

What may happen during a foot and nerve assessment?

The assessment may include:

1. Symptom history. When the symptoms started, whether they are symmetrical, what makes them worse and whether there is weakness, back pain, imbalance or a wound.
2. Medicine and health review. Diabetes duration and treatment, glucose history, alcohol exposure, kidney and thyroid history, prior surgery and medicines that may affect nerves or vitamin levels.
3. Skin and footwear inspection. Cracks, callus, fungal changes, pressure areas, blisters, ulcers, shoe fit and foot deformity.
4. Neurological examination. Light touch, pressure sensation with a monofilament, vibration, temperature or pin sensation, reflexes, strength and gait as clinically appropriate.
5. Circulation assessment. Foot temperature, colour, pulses and other findings that may suggest reduced blood flow.
6. Targeted investigations or referral. Blood tests, vascular assessment, nerve testing, podiatry, wound care, neurology or urgent hospital care when the findings require it.

People with diabetes should receive regular foot assessment. The frequency should increase when there is loss of protective sensation, peripheral artery disease, deformity, a previous ulcer or another high-risk finding.

What should I check at home?

If you have reduced feeling, inspect both feet every day, including the soles and between the toes. A mirror or help from a family member may be useful.

• Look for redness, warmth, swelling, cracks, blisters, discharge, colour change or a new wound.
• Check the inside of each shoe before wearing it.
• Avoid walking barefoot where an unnoticed cut, burn or puncture could occur.
• Wash with comfortably warm—not hot—water and dry carefully, especially between the toes.
• Do not cut a corn or callus yourself and do not place chemical corn removers on numb skin.
• Seek professional help for an ingrown nail, callus, wound or footwear problem when needed.

These steps reduce avoidable injury but do not replace professional assessment.

When is a foot problem urgent?

Do not wait for a routine diabetes appointment if you have:

• a new ulcer, open wound, black or blue skin, or tissue that appears dead;
• spreading redness, warmth, swelling, pus, bad odour or fever;
• a hot, swollen or misshapen foot, especially with little pain;
• sudden loss of movement or sensation;
• severe foot pain with a cold, pale or discoloured foot; or
• rapidly worsening weakness, loss of bladder or bowel control, or numbness around the groin.

These findings may require urgent hospital, vascular, neurological, surgical or specialist foot care.

Can nerve pain be treated?

Treatment depends on the cause and the patient’s other conditions. It may include improving diabetes and cardiovascular-risk management, correcting a confirmed deficiency, changing a contributing medicine when appropriate, treating a compressed nerve, protecting an at-risk foot and considering medicine for neuropathic pain.

Pain-relieving medicines can reduce symptoms for some people, but they do not repair every form of nerve damage. Choice and dose require individual review because sedation, falls, kidney function, other medicines and pregnancy considerations may affect safety. Do not start, stop or increase a medicine based on this page.

What should I bring to the appointment?

• Your current medicine and supplement list.
• Recent HbA1c and glucose records or a CGM report, if available.
• Relevant kidney, thyroid, vitamin B12 or other test results.
• A short note describing where the symptoms occur and when they are worst.
• The shoes you wear most often if pressure or fit may be contributing.
• Details or photographs showing how a wound has changed, while protecting your privacy.
