sunnyb, I can only give you my past experience with Prednisone. Basically good. On bad days I was say real stiff and sore. I would take 15-20mgs and later that day I was about back to my usual self.
I have had RA for about 18-19 years. I too, am taking methotrexate, (7) 2.5mg pills once a week. I have been successful on that too. Of course about every 6-7 weeks I have my liver checked. BTW, I guess you know that predisone is not good for you. (what is these days?) My previous doctor said I should try to take only when necessary. I plum just quit taking it, but if your doc says to stay on it, then I would or really it's up to you. You don't have to take them if they're not helping you.
Other questions. How long have you been diagnosed? How long have you been on Methotrexate? Does it help you? Methotrexate is a drug you may have to take for the rest of your life unless you go into remission. That would be a miracle.
My hands look bad, some fingers are immobile. Feet are bad. It's basically all over. Good luck to you.
