Hi: I am experiencing a prolonged fever for about two weeks, returning even after I have taken fever reducers. I also am keeping a headache, having night sweats, suffering with nausea and diarrhea, tasting metal in my mouth, and having pain in my back. I have gone to a med center, and they confirmed my fever is not going down (stays between 101 - 102 temp). Any thoughts on what I should be asking the physician about?
