i have been told that i have chronic fatigue/autonomic dysfunction by a very prominent infectious disease doc who treats many cfs patients. i work with a team of about six doctors, all of whom agree that my illness is from a virus or infection. my initial symptoms began shortly after having lived in africa, and included very swollen lymph glands, swollen arthritic joints and a very stiff neck. i no longer have any joint inflammation, but two years later, i still get very swollen glands and a stiff neck. all my doctors refer to this "virus or infection" that i had/have. my ID doc tested me for 18 viruses/infections known to cause cfs, like all the herpes, epstein barr, cmv, mycoplasma and others. i was negative for all. so i'm left wondering WHAT virus or infection all these docs are alluding to? it seems pretty apparent to me that i did have some kind of viral or infectious process going on, but what????? i am wondering if anyone can suggest other tests, other viruses known to lead to such disorders?
