I am trying to get off prednisone. I get to two mg's and then flare. what else can I take..

I have had Ra for 3 Years.  I am on Methatrexate, 25 mg, Remicade, 300mg, and Prednisone 5 mg.  I am trying to get weaned off the prednisone.  I have tried it the last two years and when I  get to 2 mg, I flare.   Currently, I am at 3 mg.   I feel achy and are having problems with my feet and lower back.  Is there anything else I can take in place of the prednisone? 

My RA is under control and I dont have any severe pain.  I am afraid I will flare again and be back at square one.   But, I dont like the way I feel now at 3 mg.   At 5 mg , I feel great.   I would appreciate your advise.   k. tate
