Meralgia paresthetica is a condition characterized by tingling, numbness and burning pain in the outer thigh. These symptoms may become worse after walking or standing. The condition generally only affects one side of the body, although both sides may be involved in up to 20% of cases. Meralgia paresthetica is caused by compression of the lateral femoral cutaneous nerve (a sensory nerve to the skin on the outer thigh). This may be associated with a variety of causes such as tight clothing, obesity, and/or pregnancy. Treatment is based on the signs and symptoms present in each person and may include medications to manage pain. In most cases, conservative treatment by wearing looser clothing and/or losing weight generally resolves symptoms.
