Meralgia paresthetica is a condition characterized by tingling, numbness and burning pain in your outer thigh. The cause of meralgia paresthetica is compression of the nerve that supplies sensation to the skin surface of your thigh. <\/p>\n
Tight clothing, obesity or weight gain, and pregnancy are common causes of meralgia paresthetica. However, meralgia paresthetica can also be due to local trauma or a disease, such as diabetes. <\/p>\n
In most cases, meralgia paresthetica can be relieved with conservative measures, such as wearing looser clothing. In severe cases, treatment may include medications to relieve discomfort or, rarely, surgery.<\/p>\n
Meralgia paresthetica occurs when the lateral femoral cutaneous nerve — which supplies sensation to the surface of your outer thigh — becomes compressed, or “pinched.” The lateral femoral cutaneous nerve is purely a sensory nerve and doesn’t affect your ability to use your leg muscles. <\/p>\n
In most people, this nerve passes through the groin to the upper thigh without trouble. But in meralgia paresthetica, the lateral femoral cutaneous nerve becomes trapped — often under the inguinal ligament, which runs along your groin from your abdomen to your upper thigh. <\/p>\n
Common causes of this compression include any condition that increases pressure on the groin, including:

Pressure on the lateral femoral cutaneous nerve, which supplies sensation to your upper thigh, may cause these symptoms of meralgia paresthetica:

\nThese symptoms commonly occur only on one side of your body and may intensify after walking or standing. <\/p>\n
