I'm sorry you are feeling so bad. I have to say you have more patience then I do. I'd be calling tomorrow. At least to find out just exactly how long this test is supposed to take. I mean even if they are backed up some tests have to be done in a certain amount of time or they won't be any good. Even without test results I don't see why your doctor doesn't do anything to treat your symptoms. That is what they usually do anyway. Most of them treat autoimmune disease with the same drugs Putting you on a low dose of steroids and plaquanil shouldn't be a problem. But I'm no doctor.
good luck and let us know what you find out
You learn to love and live
you fight and you forgive.
you face the darkest night.
just live before you die.
