Hi Mandolyn and Welcome, I'm sorry you cannot get a specific diagnosis. I think Lynnwood is soooo right. My doctor went around everything he could and wasn't even going to give me a diagnosis until I ask him directly myself.
He told me that on my chart he was going to put down Inflammatory Arthritis for insurance purposes. I was really very glad he did that because I have read on other forums that it is very hard to get insurance if you are diagnosed with SLE.
But if you google inflammatory arthritis it pretty much says Lupus. I guess it's whatever is written on your medical records that make the difference.
I would also consider going to another Rheumy to see if they can give you a specific diagnosis, especially if you want to do the Clinical Trial. Good luck. Hope you get your answers. AnnieRae
