This is Dr. David. I am reviewing your question now and will be with you momentarily.
taking antibiotics can put you at risk for clostridium difficile bowel infections which can cause diarrhea
you need your stools tested for clostridium difficile toxin. have you had that done?
you should get your stools checked for C diff toxin to see if this infection caused by your antibiotic therapy is causing your watery diarrhea.
