Hi Jases. Autoimmune diseases are a strange lot to be sure. I saw a rheumy for over a year before he would diagnose me and that was only because I argued that I had two positive anti-double stranded DNA tests. Getting to that point took two years of many symptoms. If you don't agree with your rheumy consider seeing another. I agree with Okie that some of your symptoms sound like sjogrens.
More importantly, you really should see your primary care doc asap. You may have something else. Let us know how it goes. Love, Butterflake
