Meralgia paresthetica is a neurological disorder characterized by numbness, pain, and tingling in the thigh. The disorder occurs as a result of compression or irritation of the lateral femoral cutaneous nerve. External pelvic compression and post-surgical complications can lead to meralgia paresthetica. The condition is typically treatable and rarely results in chronic damage or impairment.


1. The Lateral Femoral Cutaneous Nerve

The lateral femoral cutaneous nerve (LFCN) is a sensory nerve in the pelvis, part of the peripheral nervous system. The role of this nerve is to relay sensory messages between the thigh and the spinal cord and brain, including those of sensation and pain. The LFCN originates at the lumbar nerves and travels through the pelvic region of the body, exiting into the thigh.
