HI Cosmic, What's you name
I'm Lorna, I have had RA for just over 4 years now. The rash could be your body getting used to the drugs you now take. I had a rash everywhere when I first started the triple therapy. I was told to stop all and re start slowly but all settled down after that. Get advice from your doctor or consultant then you should settle down. It could also be due to a flare up, your skin can go red and inflamed when the flare up is bad.
Don't despair it will get easier to deal with. Do a little each day and rest in between until you get on top of things. Always remember to pace yourself, easier said than done I know. Keep posting.
Take care Lorna x
