Quick Reference

A condition characterized by a dull ache in the mid-buttock region, night pain, and pain when walking upstairs. Symptoms increase when sitting, walking, or running, and decrease when supine. It is due to entrapment of the sciatic nerve within the piriformis muscle and may be related to any irritation that causes the muscle to spasm and constrict the nerve. The sciatic nerve passes directly through the pirformis of about 20% of the population making them susceptible to this form of nerve entrapment. Appropriate stretching exercises. Non-steroidal anti-inflammatories, ultrasound, aggressive massage, and, occasionally, steroid injections, have been used to treat the syndrome. Surgical release of the piriformis was common in the past, but conservative treatments are now generally preferred.
