I am in the middle of trying to afford the tests to diagnose if I have MS of something different. I have many symptoms of MS, but the main symptom is spasticity in the legs, feet, which I can verify is very painful. For me it is five years now, and getting worse. The doc treats me like I have MS, I use baclofen and zanaflex everyday again at night, as well as daypro for pain and inflamation. I have used oxacodone but it didn't touch the pain, it just made me not care. So I don't take that. I take prednisone when everything else doesn't work to put whatever this is into remission, and it does work, but with side affects. I definitely feel for you. If you need write me . I don't know what great advice to tell you, but you are the first person I've run into that sounds similar to my situation.
Take care,
Chad
