I have also tried Medrol-DosePak, Indomethacin, Daypro, Flexaril, Darvocet
Robaxin. They had no effect on my condition or pain.
Your situation is quite complex. It sounds like your doctors were looking for the right things: arthritis in the hips, compression of nerve roots in the lumbar spine, etc.
My experience is often that a large amount of pain can accompany minimal lesions.
