I am a GI nurse and have been dx with Diverticulitis, I have been on Augmentin 875mg bid x 6 days and the pain became worse then my doctor put me on Cipro 500mg bid and Flagyl tid, I have been on that course for 2 days, I know have bad tailbone pain and pressure. I am afebrile, no vomiting, just the increased tailbone and inguinal pain. Could this be early signs of a perforation?
