Tyno I know you have been through a lot so I'm glad your taking care of YOU now.
Your former doc should have tested for RA when he was ruling out other things it could have been. I know when my RA came back high and I was sent to a rheumy he checked my joints to look for redness and swelling which is a sign of RA. Mine came back high due to Sjogren's and now Celiac. I have bad osteo arthistis in my hands and other places but not RA.
There are so many of us on here with auto-immune disorders and fibro there has to be a connection somewhere. My DIL was dxd with RA long before fibro and a friend of my son's was dxd with lupus and fibro, they are in their early 30s.
Anyway I'm glad you found a new doc that is taking an interest in you.
luv and hugs
