Sounds as if the Rheumy is looking into things well enough. You're with the best person to DX whatever is going on with you.
Having only 2 of the 11 symptoms may be a very good thing. You need to have at least 4 of the 11 to have lupus. Like Lynnwood said a lot times they treat the symptoms then figure out the disease. A lot of times people with have some symptoms and never get lupus either. My daughter has had a positive ANA since she was 7 and she's now 21. She still hasn't been DX'd with lupus and she's now 21.
Lupus is know as the disease with a 1,000 faces so you certainly could have something other than lupus. Good luck with your testing and I hope they can figure out why you're not well. Take care and let us know the results.
