My usual recommendation for finding a good rhuemy, if you don't already have one, is this:
Visit
www.lupus.org and find your local chapter. Get in touch with your local chapter and get the list of rheumies that are active on the advisory board. These are the Drs in your area that are interested in Lupus & in treating Lupus.
A diagnosis can take years, but often Drs start treatment (most likely with Plaquenil and possibly Prednisone) to see how you respond before they finalize a diagnosis.
Best way to determine your rheumies game plan is to ask her!! Different Drs approach things differently. I had a lot of muscle weakness & joint pain.
I got a "proper diagnosis" within 4-6 months of my GP first suspecting something auto-immune and sending me to a rheumy. (Later I discovered that I'd been sent to the MOST respected rheumy in a 6 million person metro area, so that may have been a huge factor.)
Let us know how it goes.
