I am taking MXT for helping lower my steroids and also for my RA, although it doesn't show up in blood tests. I have polymyalgia but my blood tests have been good for some time. I am waiting to start Etanercept and am finding I am becoming more and more exhausted and feel like a zombie. Also my RA pain is becoming worse and when I try and lower my steroids I can't lift my arms higher than out straight in front of me and can hardly walk, so I increase the steroids again. I have been told to stay on MTX even though the rheumy wrote to my Dr that I am not tolerating it. I think it's affecting my breathing too. Would I be wrong to not take it any more if it's not working and causing side effects?
