Meralgia paresthetica after strenuous exercise.

We present three patients with signs and symptoms of meralgia paresthetica (MP) after long-distance walking and cycling.

A neuropathy of the lateral femoral cutaneous nerve was confirmed in all patients with somatosensory evoked potentials. We propose that conduction block due to local ischemia during repetitive muscle stretching was the probable cause for the neuropathy
