Hi Jean, yes predisone is one of those love/hate kind of drugs lol. as for the plaq. yes it is true it does take a long time. At least it did for me. I can't exactly say when it started to work. It was very suttle. After about 6 months I realized that I could put a t shirt on instead of a button up blouse. I couldn't lift my hands over my head before. I also noticed that my legs didn't feel like lead weights anymore. I sure it started to help earlier then 6 months but that's when i noticed it. It's not a miracle drug. I still have lead legs and painful joints I just don't have them every day. Hopfully your doctor can give you something to help you now.
