What causes leg burning sensation?
Leg burning sensation can be caused by nerve or skin damage in the legs and surrounding tissues. Burns from chemicals or extreme heat, as well as exposure to poisonous substances, may damage the nerves in the skin, resulting in a sensation of leg burning.
Damage to the peripheral nerves (peripheral neuropathy) can also cause a leg burning sensation. Peripheral neuropathy may be due to specific diseases or conditions, such as diabetes or alcoholism, that can affect nerve health, or it may have no known cause.
Physical causes of leg burning sensation
Leg burning sensation may be due to physical causes including:
- Burns, including sunburn
- Exposure to cold
- Exposure to toxic or poisonous compounds
- High-intensity exercise
- Leg injury
- Pressure on nerve
Diseases or disorders causing leg burning sensation
A number of diseases can cause burning legs including:
- Alcoholic neuropathy (nerve damage associated with excessive alcohol consumption)
- Diabetic neuropathy (nerve damage due to high blood sugar levels associated with diabetes)
- Guillain-Barre syndrome (autoimmune nerve disorder)
- Meralgia paresthetica (pain in outer thigh due to nerve compression)
- Multiple sclerosis (disease that affects the brain and spinal cord causing weakness, coordination, balance difficulties, and other problems)
- Peripheral artery disease (PAD, also called peripheral vascular disease, or PVD, which is a narrowing or blockage of arteries due to a buildup of fat and cholesterol on the artery walls, which limits blood flow to the extremities)
- Rheumatoid arthritis (chronic autoimmune disease characterized by joint inflammation)
- Shingles (reactivation of the varicella-zoster virus, which remains in the body in an inactive state following chickenpox)
