While fatigue or a skin infection can cause temporarily burning or inflamed feet, burning feet are most often a sign of nerve damage (peripheral neuropathy). Nerve damage has many different causes, including diabetes, chronic alcohol use, exposure to certain toxins, certain B vitamin deficiencies or HIV infection.

Possible causes of burning feet:

• Alcohol use disorder
• Athlete's foot
• Charcot-Marie-Tooth disease
• Chemotherapy
• Chronic kidney disease
• Complex regional pain syndrome
• Diabetic neuropathy (Nerve damage caused by diabetes.)
• HIV/AIDS
• Hypothyroidism (underactive thyroid)
• Tarsal tunnel syndrome
• Vitamin deficiency anemia

Seek emergency medical care if:

• The burning sensation in your feet came on suddenly, particularly if you may have been exposed to some type of toxin
• An open wound on your foot appears to be infected, especially if you have diabetes

Schedule an office visit if you:

• Continue to experience burning feet, despite several weeks of self-care
• Notice that the symptom is becoming more intense and painful
• Feel the burning sensation has started to spread up into your legs
• Start losing the feeling in your toes or feet

If your burning feet persist or if there is no apparent cause, then your doctor will need to do tests to determine if any of the various conditions that cause peripheral neuropathy are to blame.
