What is piriformis syndrome?

The piriformis muscle lies in the lower buttocks area between the sacrum and hip. The sciatic nerve runs below or through the piriformis muscle. Piriformis syndrome will mimic sciatica. With piriformis syndrome, there is no weakness or numbness. Piriformis syndrome is typically caused by an injury to the piriformis muscle and often does result in irritation of the sciatic nerve that runs near it. It is typically treated with anti-inflammatories, stretching exercises, and sometime massage techniques such as sitting with a tennis ball underneath the affected area. Resistant problems can be treated with steroid injections, sometimes Botox injections, and /or even surgical resection of the piriformis muscle.
