My symptoms have settled down a bit after taking a 3 week dose of prednisone. During a bad flare I have extreme pain in my upper arms. It does not feel like it is in the shoulder joint. It is so bad I can't sleep and I cannot even brush my hair. I mentioned it to my doc, but he seemed baffled. What could this be? I am on 10 tabs metho, paquenil(?), folic acid and I take Aleve.
