Burning Feet
A sensation of heat or burning in the feet
Quick Facts
- Type: Sensory nerve symptom
- Common causes: Diabetes, B12 deficiency, nerve compression, alcohol use
- Often worse: At night
- See a doctor: If persistent, worsening, or with numbness
Overview
Burning feet is the sensation that your feet feel hot, on fire, or uncomfortably warm, even though they may look normal and feel cool to the touch. The feeling can be mild and occasional or intense and constant, and it often becomes more noticeable at night. Some people also feel tingling, pins and needles, or sharp pains along with the burning.
Occasional burning after a long day on your feet or from tight shoes is usually nothing to worry about. Persistent burning feet, however, most often comes from a problem with the nerves that supply the feet, known as peripheral neuropathy. Diabetes is the most common cause, but there are others, and many respond to treatment, so it is worth finding out what is behind it.
Common Causes
Burning feet usually reflect nerve irritation or damage, though other factors contribute:
- Diabetes: The most common cause, as high blood sugar over time damages the nerves in the feet.
- Vitamin B deficiencies: Particularly low vitamin B12, which is important for nerve health.
- Nerve compression: A pinched nerve in the foot, ankle, or lower back.
- Alcohol use: Heavy drinking can damage nerves over time.
- Thyroid and kidney problems: Both can affect the nerves.
- Infections: Such as athlete's foot, which can cause burning of the skin.
- Poor circulation: Reduced blood flow to the feet.
- Medications: Some drugs, including certain chemotherapy agents, can cause burning.
Associated Symptoms
Burning feet often come with other sensations that help identify the cause:
- Tingling or pins and needles
- Numbness or reduced feeling
- Sharp, stabbing, or shooting pains
- Redness, warmth, or swelling of the feet
- Increased sensitivity, where even light touch hurts
- Weakness or unsteadiness
Burning in both feet that creeps upward suggests neuropathy, while burning with itching, peeling, and redness of the skin between the toes suggests a fungal infection like athlete's foot.
Diagnosis & Evaluation
A doctor evaluates burning feet by looking for nerve or skin causes:
- Examination: Checking sensation, reflexes, circulation, and the skin of the feet.
- Blood tests: For blood sugar, vitamin B12, thyroid and kidney function.
- Nerve studies: Nerve conduction tests and electromyography when neuropathy is suspected.
- Skin assessment: Looking for fungal infection or other skin causes.
Pinpointing the cause guides treatment and helps prevent progression.
Treatment & Management
Treatment targets the underlying cause and eases the burning:
- Controlling blood sugar in diabetes to protect the nerves.
- Replacing vitamin B12 or other deficient nutrients.
- Reducing alcohol if it is contributing.
- Treating infections such as athlete's foot with antifungal medication.
- Medications for nerve pain when burning is significant.
Self-care can bring relief too: soaking feet in cool water, wearing well-fitting, breathable shoes, keeping feet clean and dry, and elevating them at the end of the day. If you have diabetes, check your feet daily, since reduced sensation can hide injuries.
Self-Care & Prevention
Caring for your feet and nerves can ease burning and prevent it from worsening, particularly when a condition like diabetes is involved. Useful steps include:
- Keeping blood sugar well controlled if you have diabetes
- Eating a balanced diet with enough vitamin B12, and correcting any deficiency
- Limiting alcohol, a common cause of nerve damage
- Wearing breathable, well-fitting shoes and moisture-wicking socks
- Keeping feet clean and dry to prevent fungal infections that can burn
- Soaking feet in cool water and elevating them at the end of the day for relief
- Checking your feet daily for injuries if your sensation is reduced
Because burning often signals nerve changes, addressing blood sugar and nutrition early offers the best chance of preventing further damage. Protecting numb or burning feet from unnoticed injury is equally important.
When to See a Doctor
See a doctor if burning feet are persistent, worsening, spreading up the legs, or come with numbness, weakness, or open sores. People with diabetes should report new burning or numbness, since reduced sensation raises the risk of unnoticed foot injuries and infections.
Seek prompt care if your foot becomes red, swollen, warm, and painful with fever, or if you develop a sore or wound that is not healing, as these can signal infection that needs urgent treatment.
Frequently Asked Questions
What causes a burning sensation in the feet?
Burning feet are most often caused by nerve damage, called peripheral neuropathy, with diabetes being the leading cause. Other causes include low vitamin B12, a pinched nerve, heavy alcohol use, thyroid or kidney problems, and fungal skin infections. Persistent burning should be evaluated.
Can burning feet be a sign of diabetes?
Yes. Burning, tingling, or numbness in both feet is a common early sign of nerve damage from diabetes. If you have burning feet along with increased thirst, frequent urination, or fatigue, ask your doctor to check your blood sugar.
How can I relieve burning feet at home?
Soaking your feet in cool water, wearing breathable, well-fitting shoes, keeping feet clean and dry, and elevating them can ease burning. If burning is persistent or comes with numbness or weakness, see a doctor to treat the underlying cause rather than relying on home measures alone.
Why are my feet burning at night?
Burning feet often feel worse at night because there are fewer distractions and the warmth of bedding can intensify the sensation. Nighttime burning is common in nerve-related causes like diabetic neuropathy. If it disrupts sleep, mention it to your doctor.
When are burning feet a medical concern?
See a doctor if burning is persistent, worsening, or comes with numbness, weakness, or sores, and seek prompt care if a foot becomes red, swollen, warm, and painful, or you have a non-healing wound. People with diabetes should report any new foot symptoms.
