Psa, fibromyalgia, lupus, addisons? how do i find out?

See a rheumatologist: I assume you want to know whether you have any of those three. Your best bet is to see rheumatologist to help clarify your correct diagnosis. The fact that you have stated these diagnoses, i would question whether you've already been given the diagnosis by an other physician.

Doctor : You need to establish a relationship with a doctor who will take a thorough history and physical and examine you and then order the appropriate test. Good luck.
