Sciatica is a commonly treated condition at the physio clinic. It involves pain along the sciatic nerve, which runs from the lower spine (lumbar spine) down to the foot. The pain can occur anywhere along the path of the nerve, so it may present as buttock pain, foot pain, or a combination of both. The pain can be aching, sharp, or tingling, and you may also experience pins and needles or numbness along the nerve’s pathway. The sciatic nerve exits the lower spine, runs through the buttock, down the back of the thigh, and into the lower leg and foot.
