Meralgia Paresthetica

Meralgia Paresthetica is a condition in which the lateral cutaneous nerve of the thigh (L2-L3) is entrapped at the inguinal ligament causing tingling and numbness on the antero lateral aspect of the thigh.

It occurs primarily in men but in women it is usually associated with pregnancy. Obesity and diabetes predispose to the condition.

Prolonged standing or walking may exacerbate the condition.

The nerve is tender on pressure at the point when it passes below the inguinal ligament.

Numbness and tingling is felt in the skin, which may be extremely hyperaesthetic. The symptoms are usually unilateral and there are no motor signs.

Most cases of Meralgia Paresthetica resolve spontaneously. Analgesics are helpful. In severe cases decompression may have to be done.
