I have worked around people with cdiff for many years, and it is not a fun thing to get. Cdiff usually looks a little gelatin like, and the smell is BAD. Lots of loose stools too, and yeah, you'd have abdominal discomfort. NOW, I have never had it myself, so I can't speak from that angle. If they get looser and start to smell badly (different from normal) then yes, you may want to see your dr. If you are really concerned, you could go ahead and make an appt. You'll have to take a stool sample with you I'd bet, so be sure to ask if you can get the appropriate collection materials BEFORE your appt. Good luck to you!
