I'm currently on MTX and humira and my joint pain and swelling haven't gotten better since re starting mtx but pred actually makes it worse!!!!! I was actually disgnosed with RA while I was on a 3 month dose of pred.
I got off of MTX for 3 months to try and have a baby but with in 5 weeks of stopping it the arhtritis got out of control i went crippled basically. So I gave up and went back on it but this time around it just isn't doing it :(
But if it helps you I'd say do it... worth the side effects.... I'd do anything right now for some relief like I had last year
good luck and let us know what the doc says!!
