Piriformis syndrome is often confused with sciatic nerve pain. A true piriformis syndrome occurs when the piriformis muscle compresses or irritates the sciatic nerve as it runs through the muscle. The irritation of the nerve can cause numbness, tingling and pain along the outer hip and along the back of the thigh. The most common cause is due to tightness of the piriformis muscle.
Signs & Symptoms:
Pain and numbness increases with activities that involve contraction of the piriformis muscle and by prolonged sitting
Physiotherapy—a physiotherapist may use modalities such as TENS, acupuncture, ultrasound, manual therapy and exercise prescription
Massage therapy—massage techniques applied directly to the piriformis muscle will increase the circulation and separate the muscle fibres to release the muscle tension
