I am diagnosed RA, but not 100% as it does not show up in bloodwork. I was on Enbrel for 5 months and it was a miracle almost from the get go but then stopped working after 3 months. Then I went back on Prednisone and started Humira 5 weeks ago and no help at all. The first 3 weeks I was nauseous and throwing up. One day I am fine and have a great appetite but feel acidy all the time.
