I started taking 15 mg of predisone and within a week I was 80 percent better. I could not get out of bed so it was like magic in 7 days. I have always exercised and was down for 2 days and made myself get moving again (cycling) and it helps enormously with pain. I am a little stiff in AM but after a 2 hour ride on a road bike at night I am almost back to the old me except the creepy prednisone feel. Everyone is different but ---- moving is crucial.
