There is a piriformis muscle located in each buttock. The piriformis muscles are deep and are responsible for rotating our feet outwards. Due to the proximity of the piriformis muscles to the sciatic nerves problems can and do occur. If the piriformis muscle goes into spasm it can choke or press on the sciatic nerve causing pain to radiate down into the leg(s). If you are experiencing sciatica it may be due to a piriformis spasm. You should have this evaluated to determine what is causing your leg pain. This is a common syndrome that I have treated many times. If you live in the greater Cincinnati area and are experiencing leg pain give me a call.
