I would say it's just from the antibiotics on your system. C Diff is pretty violent and at the nursing home we only send out a sample to be tested if they have 15 or more diarrhea episodes a day. I have taken care of people with c diff who sit down to go, you no sooner pull their pants up and they're going again. It's awful! I would eat some yogurt, continue your probitoic and eat light until you feel better !
