Although there are 100s of bad side effects of Prednisone there are 100's of good things it can do. I was diagnosed with Fibromyalgia in 1991 and 2 years ago my doctor changed that to Polymialgia which is treated with Prednisone. Anyone who actually has Fibromyalgia knows the constant joint pain which is the same ache you have when you have the flue, they will also know about the constant low grade fevers that come with Fibromyalgia, and a bunch of issues. My doctor put me on 15mg of Prednisone and my body aches went away for the first time in more than 40 years. Unfortunately the increase in eye pressure got it reduced to 10mg and it is no longer working. At 15mg I could go to the bathroom normal no more constipation to diarea all week long. I am back to that. Dumb eyes
