Thanks for the info. It helps to understand the big picture.
I think Pred is a wonder drug in certain situations. Before I went on Humira [about 15 years ago], and the MTX by itself wasn't working well, I was getting corticosteroid shots in many of my major joints. It was a godsend. However, FOR ME, Pred pills make me rebound when I get off them. [I've had to go on the Pred pills for COPD bronchitis flares.]
Pred is not meant as a long term solution. It's to get you over the hump - translation.....maybe a month. So hopefully you will discuss weaning off the Pred with your rheumatologist. At the same time you might want to discuss with him/her starting biologics, which are targeted for RA. While Pred may make you feel somewhat better, it doesn't do quite the job of arresting RA.
