Oh, Mary, I feel for ya girl. First of all, know that you'll be in my prayers! Secondly, if your docs are puzzled, keep talking to them to investigate more, or find another doc that will partner with you. I have lupus too, and have belly pain like a bee sting type feeling, across my abdomen. Your chest wall pain might be inflammation or pluresy - really common during a flare. Rash could be from lupus flare, too. I also wondered about shingles when you described the rash & the pain. Have you ever had chicken pox? If so, then your immune system can go a little nuts and you end up with shingles. Hurts like heck, but can be treated with anti-viral meds if caught early enough. Either way, know you aren't alone and that you're NOT CRAZY!! You know your body well enough to know somethings not right. Maybe this isn't the right rheumatologist for you.Remember also that autoimmune things like lupus can sometimes take forever to figure out, even by the best docs. It's a process, not just one simple test. Please try to hang in there and know I'll be prayn for pain relief for you! Hope this helps!
