Causes of burning sensations, often described as tingling, in the leg include medical conditions, environmental factors and certain types of substance abuse. Burning sensations within the leg may also signal an underlying complication or condition that requires medical treatment. In some cases, pain may resolve without medical intervention.
Multiple Sclerosis
Multiple sclerosis can cause burning sensations in the leg. This disease occurs when the immune system attacks the protective coating, called the myelin sheath, surrounding the nerves. Without the protective coating of the nerves, communication between the body and brain is interrupted. Multiple sclerosis can cause irreversible nerve damage. Symptoms vary based on the nerves affected and extent of the damage. According to MayoClinic.com, common symptoms and signs of multiple sclerosis include burning or tingling pain throughout the body, weakness or numbness in one or more limbs, fatigue, dizziness, loss of coordination and vision problems.
Sunburn
Sunburn is another condition that can cause burning sensations within the leg. Sunburn is characterized by skin reddening following continuous exposure to ultraviolet light or the sun. Evidence of sunburn may not appear until several hours after sun exposure. Sunburn occurs when prolonged sun exposure surpasses the ability of melanin to protect the skin, reports MedlinePlus. Melanin is the protective pigment in the skin.
Alcohol Neuropathy
Alcoholism, also known as alcohol dependence, can create burning sensations in limbs such as the legs. The National Institute on Alcohol Abuse and Alcoholism describes alcoholism as a disease that is characterized by the inability to stop drinking, strong urges to drink, physical dependence on alcohol and the need to consume excessive alcohol to achieve the desired effect. MedlinePlus defines alcohol neuropathy, a complication of alcoholism, as nerve damage resulting from excessive alcohol consumption. Common symptoms and signs of alcoholic neuropathy include burning sensations, pain, numbness or tingling in the arms and legs; heat intolerance; difficulty urinating; nausea; vomiting; and muscle weakness. Although alcoholism cannot be cured, it may be successfully treated.
