Hi Jej. Sorry for your rheumatologist. I'm in the process of changing because of the attitude of the previous one, I won't tolerate that from a physician anymore. I assume you've had complete CBC and other blood and urine panels. Have you had Immunoglobulins (A, E, G, M, etc) checked? I hate to bring up the 'C' word (my wife has 2 we're dealing with) but has that been ruled out? Have you had a complete set of skeletal x-rays? Good luck.
