my dad has one for his lupus and rheumatoid arthritis.
they specialize in the diagnosis and treatment of arthritis and other diseases of the joints, muscles and bones. Many rheumatologists conduct research to determine the cause and better treatments for these disabling and sometimes fatal diseases. some of those diseases are rheumatoid arthritis, osteoarthritis, gout, lupus, back pain, osteoporosis, fibromyalgia and tendonitis.
i can't tell ya what to expect from a first visit. but most likely there will be blood work and paper work and checking vitals. i also looked it up. it says to make sure ya have a full list of medications you are taking and to expect a full examination and for you to try to have previous x-rays already available and that there is a possibility of diagnostic tests ordered to pinpoint the problem.
whatever is going on--i hope it aint too painful and works out wellf or you..
