Un-diagnosed?

I went to my Rhemy appointment (he is part of a Lupus treatment centre) and he bascially said my other doc was wrong. While the blood tests are positive, he is sure everything else is working the way it should and he is not ready to stamp "LUPUS" on my chart. While this is a happy moment, I am also left with the migraines and the tiredness and occasional sadness (which I know is definately not from circumstance/personality).

having read how so many people have battled to get their doctor's/diagnoses right - now I am wondering which of the two doctors was right
