My friend in rural Alabama had to get his PCP to send him to the closest Mayo Clinic fror a diagnosis, because when he went to the ER for his rash and yellow skin they flat out refused to believe he had Lupus. He has RA because of the lupus, severe allergies, sensitivities to barometric changes...

"No one test can diagnose lupus. The combination of blood and urine tests, signs and symptoms, and physical examination findings leads to the diagnosis.

It really sounds like your doctor doesn't know enough about Lupus, and I'm sorry to hear that you'll probably have to do some travelling to get a firm diagnosis that your local Doc will accept as fact. Hugs and hopes.
