Welcome...you've come to the right place...I had a similar experience. My primary care physician took many tests Ana dsDna etc and dx'd me with lupus...I went to my first Rheumy an he told me that he liked to refer to what I seem to have as "crazy Womans disease" then proceeded to tell me that I really don't feel what I am feeling.
I suggest if you don't really care for the Rheumy you find one you can trust and/or do care for...there may be sometimes that you will need to work with the rheumy closely and if you don't care for what he says or how he is saying it could put undue stress on you. Stress is a no no with autoimmune.
