I was on it for my rheumatoid arthritis. I am currently in remission so I am off it for now. I was also on Enbrel, I think being on both is what put me in remission.
Mouth sores are terrible, I had them really badly while on methotrexate. I found that taking folic acid helped me with them, but that could have just been the solution while on methotrexate.
I am newly diagnosed too, glad you are here.
This turned out a lot longer than I intended. TLDR: After many years of chronic pain I'm adding Fibro to my growing list of medical problems.
Went to see my Rheum today for my three-month checkup, she said my most recent pain is a Fibromyalgia flare-up and that we will treat me going forward...
