After 2 dr's I found a wonderful rheumatologist who confirmed PMR. She initially started me on 15 mg of prednisone. After nine days I was still feeling quite flu-like and some pain in my left shoulder. She suggested I try Rayos which is a time release form of prednisone. I take it at 10 pm. It releases at around 3-4am when inflammation is at its highest. I'm only on day 2 of this type of steriod so I don't have a review yet. Anyone else on Rayos?
