I had terrible diarrhea for about 15 hours the other day (about every 2 hours), then it stopped. I have been okay since. The problem is that I tested positive for c-diff (there was a nurse here for another reason and took a stool sample to the hospital for me). Then I was prescribed Flagyl (sp?). Before I take this, is it possible the stool test was wrong? I had c-diff several years ago, about 4 times and most of those stool tests were negative! Only one showed as positive, but I know they all were c-diff. I am due to have surgery on Tuesday, and I can t wait for an answer from my doc. Can I have surgery with c-diff? Please advise. Thank you.
