Meralgia paresthetica is a disorder characterized by tingling, numbness, and burning pain in the outer side of the thigh. The disorder is caused by compression of the lateral femoral cutaneous nerve, a sensory nerve to the skin, as it exits the pelvis. People with the disorder often notice a patch of skin that is sensitive to touch and sometimes painful. Meralgia paresthetica should not be associated with weakness or radiating pain from the back.
