Maybe it's time for another GI Doc? Or, since he wants to assume that your tests were positive and put you on Flagyl, go back to him and tell him that you want to assume that he cares about what you're saying and point him to this website. I'd love to get paid what these guys get paid just to assume.
Try going to www.askapatient.com and see what others reactions were to the Flagyl and why they were taking it. I don't know, I wouldn't take it because your tests were negative. Maybe someone else can give you better input than what I'm giving.
