  Piriformis syndrome, another irritation to the sciatic nerve, by Spine-Health
Piriformis syndrome is a condition in which the piriformis muscle irritates the sciatic nerve and causes pain in the rear and may cause pain along the back of the leg and into the foot (similar to sciatica pain).
Piriformis syndrome is most common among women, and is thought to be common among active individuals (such as runners and walkers).
From a technical standpoint, piriformis syndrome does not cause true sciatica (as sciatica is usually defined as a radiculopathy, or compression of a nerve root as it exits the spine).

 Piriformis syndrome - Wikipedia, the free encyclopedia
Piriformis syndrome is a neuromuscular disorder that occurs when the sciatic nerve is compressed or otherwise irritated by the piriformis muscle.
Piriformis may also become overused in situations where the gluteal muscles are not receiving enough neural drive and are not able to fulfill their role as prime mover in both hip extension and aiding the piriformis in external rotation of the femur.
Piriformis syndrome is also known as 'wallet sciatica' or 'fat wallet syndrome,' as the condition can be caused or aggravated by sitting with a large wallet in the rear pocket.

 Piriformis Syndrome: Part I
the piriformis arises from the anterior sacrum between the second to fourth anterior sacral foramina, from the margin of the greater sciatic foramen and from the anterior surface of the sacrotuberous ligament, the anterior sacrospinous ligament and the capsule of the sacroiliac joint.
Since the piriformis muscle is an external hip rotator when the hip is in extension and an abductor when the hip is in flexion,9 external hip rotation should be tested with the patient supine with the legs hanging off the table edge at the knees.
Pressure on the piriformis by way of rectal or vaginal examination may reproduce the symptoms.3 A positive "piriformis sign" due to piriformis contracture may be seen by the persistent external rotation of one lower extremity when the patient is supine.

With the hip extended, the piriformis muscle is the primary external rotator; however, with the hip flexed, the piriformis muscle itself becomes a hip abductor.
