Hi Thanks for writing The burning sensation in leg is caused by any disease which interferes with the blood and nerve supply of the legs. Although many medical conditions can cause burning feet, Diabetes is the most common cause leading to nerve damage that is neuropathy. In neuropathy, the leg nerves tend to become damaged first, at their furthest ends in the feet. This leads to tingling and numbness in the feet as well. Do you smoke and take alcohol because there consumption may lead to burning sensation in feet. Beside diabetes other common causes are- Infection of foot especially fungus (athlete foot) Chronic kidney disease (uraemia) Vitamin deficiency (vitamin B12 and occasionally vitamin B6) Alcohol abuse Low thyroid hormone levels Vasculitis (inflammation of blood vessels) My advice for you would be get following blood test done to find out the cause - Urine routine and microscopic test, Thyroid profile, Level of vitamin B12, Blood urea and serum creatinine level. Beside these blood test you need a physical examination so it is my advice to visit a local doctor. . Take care and I shall be glad to answer any further query Regards Dr.chugh
