The sciatic nerve divides above the piriformis muscle; one portion passes through the piriformis, the other leaves the pelvic area above the muscle. The sciatic nerve divides above the piriformis, one portion travels in front of it, the other travels behind it.
Does the sciatic nerve go through the piriformis?
The sciatic nerve is a thick and long nerve in the body. It passes alongside or goes through the piriformis muscle, goes down the back of the leg, and eventually branches off into smaller nerves that end in the feet. Nerve compression can be caused by spasm of the piriformis muscle.

The sciatic nerve emerges inferior to the piriformis muscle and descends in the inferolateral direction. The variations in division of the sciatic nerve, abnormal origin of piriformis muscle, and their relations in all the specimens were carefully observed, noted, and photographed.
Does walking help piriformis syndrome?
Walking is a surprisingly effective approach for relieving sciatic pain because regular walking spurs the release of pain-fighting endorphins and reduces inflammation. On the other hand, a poor walking posture may aggravate your sciatica symptoms.
