Autoimmune diseases are weird; before diagnosis, I called it "traveling joint disease." However, I wouldn't wait for diagnosis to change some things, as it always is about chasing symptoms. If your lungs are clear and the PCP sees nothing, it is ok. I like moist heat (microwaveable bed buddy), lidocaine patches, and sometimes a cold patch. Magnesium ointment or pills (350mg daily), biofreeze can also help. Diet to non-processed, low sugar, moderate wheat, potatoes, tomatoes, diary--eat good quality foods. Exercise: attached is a you tube person I like, whose movements are very much like PT (which I also suggest) and/or a massage. If your images do not seem like there is back or shoulder damage, a chiropractor might get things aligned again. Ergonomics, posture really matter, here. I have a spring type mattress with a 3", 3lb density topper. Look at your situation and see if there's anything else that may have caused overuse. I am on zoloft to help with focus, use EFT tapping and intentional breathing to destress. Take care.
