A common but little known cause of back and leg pain is piriformis syndrome. The piriformis muscle runs between the sacrum and pelvis, and the top of your thigh bone, in close proximity to the sciatic nerve. In some people, the nerve runs through the piriformis and so can become compressed or stretched by the actions of the muscle, producing buttock and leg pain particularly when sitting. The piriformis is involved in movement of the upper leg and so how we stand and walk can cause the muscle to become strained or over contracted. If the cause of your pain is piriformis syndrome, it can be identified and addressed by a chiropractor. See a professional for self-help advice.
