Why Do My Feet Burn or Tingle With Diabetes?
Burning, tingling, pins and needles or numbness in the feet are common signs of diabetic peripheral neuropathy, a type of nerve damage caused by long-term high blood sugar. Symptoms usually start in the toes and feet and may spread upward. Numbness is especially important because it can stop you from noticing cuts or blisters, which can lead to foot ulcers.
Quick answer
- High blood sugar damages small nerves and the blood vessels that supply them, especially in the feet.
- This causes burning, tingling, sharp pain or numbness, often worse at night.
- Other causes such as vitamin B12 deficiency, thyroid problems, alcohol and kidney disease should also be checked.
- Good sugar control, foot care and medicines for nerve pain can help.
How Does Diabetes Damage Nerves?
- High glucose directly harms nerve fibres
- Damaged small blood vessels reduce nerve blood supply
- Inflammation and oxidative stress worsen damage
- Longer nerves, like those to the feet, are affected first
Common Symptoms
- Burning or hot feeling in the feet
- Tingling or pins and needles
- Sharp, electric or stabbing pain
- Numbness or reduced feeling
- Sensitivity to touch, even from bedsheets
- Symptoms worse at night
- Feeling like walking on cotton or sand
- Loss of balance
Other Causes to Rule Out
- Vitamin B12 deficiency, especially in long-term metformin users
- Thyroid problems
- Alcohol use
- Kidney disease
- Certain medicines
- Spinal nerve compression
Your doctor may order blood tests to check these.
How Is It Diagnosed?
- Detailed symptom history
- Foot examination
- Monofilament test for sensation
- Vibration test with a tuning fork
- Reflex checks
- Nerve conduction studies in selected cases
How Is It Managed?
Control blood sugar
Good glucose control slows nerve damage.
Manage other risks
Control BP and cholesterol, stop smoking and limit alcohol.
Correct deficiencies
Treat low vitamin B12 if found.
Medicines for nerve pain
Several prescription medicines can ease burning or painful neuropathy. Your doctor will choose one based on your health.
Daily foot care
Inspect feet daily, keep them clean and dry, moisturise but not between toes, and wear well-fitting footwear.
When to See a Doctor Urgently
- A cut, blister or sore that does not heal
- Redness, swelling or warmth in the foot
- Discharge or a bad smell from a wound
- Sudden change in foot shape
Key Takeaways
- Burning and tingling feet are common in diabetes.
- They are signs of nerve damage from high sugar.
- B12 deficiency and other causes should be checked.
- Good sugar control slows progression.
- Daily foot care prevents ulcers.

FAQs
Why do my feet burn at night with diabetes?
Nerve pain from diabetic neuropathy often feels worse at night when there are fewer distractions. Changes in temperature and contact with bedsheets may also trigger symptoms.
Can metformin cause burning feet?
Long-term metformin use can lower vitamin B12 levels, which may cause or worsen nerve symptoms. Your doctor may check B12 levels and recommend supplements if needed.
Is tingling in the feet always diabetic neuropathy?
No. Vitamin deficiencies, thyroid problems, alcohol, kidney disease or spine issues can cause similar symptoms. A doctor can find the cause with examination and tests.
Can diabetic neuropathy be reversed?
Early nerve damage may improve with good sugar control, but long-standing damage is often permanent. Treatment focuses on slowing progression and easing symptoms.
What helps relieve burning feet?
Good sugar control, prescribed nerve pain medicines, treating deficiencies and gentle foot care help. Avoid soaking feet in hot water, as numb feet can be burned easily.
Why is numbness in the feet dangerous?
Numbness means you may not feel cuts, blisters or burns. Small injuries can become serious ulcers or infections. Daily foot checks are essential.
