Hi again, thanks for responding. I'm sorry to say that I don't know much about the disease and from the research that I've done it seems like the doctors don't know too much either. My dad was tried on a few different meds but the one that finally got it under control was the CellCept. While it was free from the pharmaceutical company my dad was the best he had been since being diagnosed. Minimal pain and pretty good strength - for a guy in his 70's. That with a steady dose of prednisone made a world of difference. My dad can't afford $900 a month which was the quote from his pharmacy to pay out of pocket with Medicare. Just surfing the Internet and came across a website that offers a few different companies that offer medication discounts/free if you qualify. It looks legit. I'm going to talk to my dad's doctor and see what she thinks. If you haven't tried Cell Cept maybe that would be the next step. The site is Needydrugs.org
