**Core Concept**
Meralgia paresthetica is a condition characterized by numbness, tingling, and burning sensation in the lateral aspect of the thigh, typically due to compression of the lateral femoral cutaneous nerve. This nerve supplies the skin over the lateral aspect of the thigh.

**Why the Correct Answer is Right**
The lateral femoral cutaneous nerve arises from the lumbar plexus (L2 and L3 roots) and passes under the inguinal ligament to innervate the skin of the lateral thigh. Compression of this nerve can occur due to tight clothing, obesity, or a direct blow to the area, leading to the symptoms of meralgia paresthetica. The nerve's anatomical course makes it susceptible to compression, which results in the characteristic symptoms.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant as meralgia paresthetica is not associated with the radial nerve.
**Option B:** This option is incorrect as meralgia paresthetica is not caused by compression of the sciatic nerve.
**Option C:** This option is not relevant as meralgia paresthetica is not associated with the peroneal nerve.

**Clinical Pearl / High-Yield Fact**
Meralgia paresthetica can be effectively treated with conservative measures such as weight loss, avoiding tight clothing, and using a foam wedge under the inguinal ligament to relieve pressure on the nerve.

**Correct Answer:** C. Compression of the lateral femoral cutaneous nerve.
