My arthritis flares just before my scleritis, then my crohn's. It usually happens when I am tapering off Pred. Right now I have been on 7mg for 5 days when I was at eight, coming down 1mg per week. My right knee is now hurting and swelling.
It's a catch 22 when I have to walk to get rid of the weight I put on from so much Prednisone. I may have to go back up for awhile then try it again. It's a work in progress.
