I have had muscle pain starting in my hip and radiating down to my ankle for six weeks now. I had an epidural in the hip joint, then the following week I had an epidural in the L5 disc. These gave me no relief, so the doctor says it has to be a muscle problem. He keeps giving me differant drugs, but nothing is stopping the pain. It goes from a 6 to a 10 or 12 on the pain scale in a matter of seconds. What kind of doctor would treat this?
