Meralgia Paresthetica is caused by injury to which nerve?

• A. Femoral Nerve
• B. Superior Gluteal Nerve
• C. Lateral Femoral Cutaneous Nerve
• D. Obturator Nerve

Answer: (C)

Meralgia Paresthetica is a condition characterized by tingling, numbness, and burning pain in the outer thigh. This condition results from injury or compression of the lateral femoral cutaneous nerve, which is primarily responsible for sensory innervation of the skin on the lateral aspect of the thigh. The lateral femoral cutaneous nerve is a purely sensory nerve that originates from the lumbar plexus, specifically from the L2 and L3 spinal nerves. Compression of this nerve can occur due to various factors, including obesity, tight clothing, or trauma to the area, leading to the symptoms associated with Meralgia Paresthetica. Understanding the specific anatomical role of the lateral femoral cutaneous nerve clarifies why it is involved in this condition, as damage to this nerve directly affects sensation in the affected thigh region, thereby manifesting the characteristic symptoms.
