First time poster, I’ve had PMR for over a year, I was down to five prednisone when I had a relapse. It’s been a yo-yo affect since that time. I’m now on ten milligrams and suffer from muscle cramps that have caused back pain, hip and leg pain. I get additional injections for the back issue. I’m unable to exercise without my back muscles spamming. My doctor doesn’t know if the spasms are a result of PMR or some other underlying issue. He has me drinking tonic water every night now. It seemed to help, but still had a few toe cramps. We are going to start a very slow decrease in the prednisone. Thanks for any input.
