One of the more common symptoms of piriformis syndrome is pain felt in the buttocks, where the piriformis is located. If you consistently feel sharp pain in one of your buttocks, you may have piriformis syndrome. Other pain to look out for that could indicate this condition includes:  Pain when sitting, standing, or lying down for longer than 15 to 20 minutes. Pain radiating down the back of your thigh, and sometimes into the back of the calf and into the foot. Pain that improves when you move around and gets worse when you sit still. Pain that is not completely relieved by a change of position. Groin and pelvic pain. This may include pain in the labia for women and pain in the scrotum for men.  Dyspareunia (painful sexual intercourse) in women.  Painful bowel movements. The compression of your sciatic nerve caused by piriformis syndrome can cause difficulty walking. Your leg may feel weakened as well. The two main things to look for when experiencing difficulty walking include:  Antalgic gait, which means a gait that develops to avoid pain. This usually leads to limping or shortening your gait to keep from feeling pain.  Foot drop, which is when your forefoot drops without your control because of pain in your lower leg. You may not be able to pull the foot up towards your face. When your sciatic nerve becomes compressed due to piriformis syndrome, you may begin to feel a numb or tingling sensation in your foot or leg. These sensations, or “paraesthesias,” may present as “pins and needles,” numbness, or tingling.

Summary:
Monitor the source, type, and intensity of pain. Evaluate your gait. Take note of tingling or numbness.
