>>> Healing with Yoga: Piriformis Syndrome (Daily Bandha)
“Piriformis syndrome is characterized by buttock and/or hip pain that may radiate into the leg as a form of sciatica. This syndrome is thought to result from spasm of the piriformis which causes irritation of the sciatic nerve as it passes across (or through) the muscle. Spasm in the piriformis can be precipitated by an athletic injury or other trauma. The mainstay of treatment involves stretching the piriformis and its neighboring external hip rotators, with surgery to release the muscle reserved for recalcitrant cases.”

Walk your hands forward and outward to push your weight out of your upper body and into your hips and pelvis. Take five long, deep breaths.”
