Daily low grade fever & chills & flu-like symptoms are definitely all symptoms of both Lupus & RA. I was officially diagnosed with Lupus, 21 years ago & with RA, 13 years ago. The flu-like symptoms actually landed me in the hospital for over a week after my second child was born, 38 years ago. They ran every test imaginable but never found out what was wrong with me. Back then, no one knew much about rheumatic diseases. No matter what doctors believe, I think everything can be RA-related. Now I too, have lower back pain and lots of GI problems. Please stay positive, be grateful for all the wonderful people and things in life, and most importantly, try to live in the Now! xoView Thread
