Hi all, I'm back again (sorry!) I seem to be falling apart all of a sudden. I now have a chest pain (for about 2weeks) on left hand side of chest. Constant pain and if I breathe in it really hurts. I have googled and seen this too can be a side effect of RA - when the joint connecting rib to sternum becomes inflamed. Just wondered if anti had any experience if this ? (No breathlessness at all.) Thanks.
