. @nettecook I feel for all of us with the doctors' lack of knowledge and the mistakes they therefore make but yours is particularly awful. My doctor almost made two mistakes with me. Starting Vanco again when I wasn't having a relapse (i.e. no diarrhea while still testing positive) was the first; the second was suggesting i take zantac for gas pains. It took me one minute on line to find a recent mayo study that showed increased risk of C.Dif relapse for those who take zantac.. My nurse practitioner friend caught the first mistake, almost yelling at me not to take Vancomycin if i wasn't having diarrhea. When I finally got into Infectious Disease specialist and GI with C.Diff specialty things felt much better. They really seemed to know what they were talking about.
