Hello, I have been diagnosis with Rheumatoid Arthritis and I am taking Orencia and Prednisone I have been having shortness of breath and a pain in my back between my waiste and right shoulder blade. I have had the pain for 4 days and at time it is getting worse. When the pain hurts really bad I get really hot like a fever and when the pain claims down but never goes away the fever goes away. Is this something I should worry about, I have a doctors appointment on Monday but is it something I should take care of today.

Summarized question: What causes shortness of breath and back pain with Rheumatoid Arthritis?
