Piriformis Syndrome

Piriformis syndrome is entrapment/irritation of the sciatic nerve as it passes through/under the piriformis muscle in the buttock, causing buttock pain radiating down the posterior thigh (pseudosciatica), without spinal-disc disease. Pain is worsened by sitting/internal rotation. Treatment: stretching/physical therapy, anti-inflammatories, and piriformis local injection; rarely surgery.
