My girlfriends sister (she is a nurse also) has been to the hospital 3 times now each time admitted for a couple days and released. They said she has cdiff but she never tested positive, she is now on Vanco now for 1 week and has 3 weeks left to be on vanco. She is still having diarrhea, running a temp, and her white count is 18,000, it was 15,000 when discharged from hospital a week ago. Should it keep going up or should she go back to hospital, hr primary (which I think is stupid) said recheck CBC on Monday. What are your thoughts and opinions.
