Meralgia paraesthetica refers to a mononeuropathy of the lateral femoral cutaneous nerve.
Patients often describe burning, coldness, lightning pain, deep muscle achiness, tingling, frank anesthesia, or local hair loss in the anterolateral thigh region.
It may result from either an entrapment neuropathy or a neuroma involving the lateral femoral cutaneous nerve. The nerve can also be injured by mechanical compression at the level of the inguinal ligament.
Treatment and prognosis
Image-guided nerve block and steroid injection may play a role in selected cases.
