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.

Meralgia paresthetica (Greek for "painful tingling of the thigh") is a condition in which patients experience pain, tingling, burning sensations or numbness in an oval area over the front and side of the thigh; it does not result in weakness or difficulty walking. It is caused by compression of the lateral femoral cutaneous nerve in the groin and is more commonly seen in overweight patients, pregnant women, and in people who wear tight belts, tight pants or carry their wallet in their front pocket. While it can be uncomfortable, there are no definitive treatments for the condition except removing the offending factor. The symptoms typically improve over time or can result in some permanent numbness over the lower part of the thigh.
