Hi Dingleeire, I'm sorry to hear your son had c. diff. It's probably one of the most miserable things you can catch. I got it in 2010, and just in this year have had 3 flare-ups of it.
I would call the doctor and have your son go in to do a stool sample to test for c. diff. today. You don't want to do antibiotics right away, because there are only a couple of antibiotics that work for c. diff. If he builds up a defense against the Flagyl, he'll move on to Vancomycin, which is much stronger. Eventually with too much it will become ineffective. Granted, this is complete worst-case scenario and MOST LIKELY will not happen, but you just don't want to go down that route.
See if he's c. diff. positive in the stool sample first. Sometimes loose stools can just happen, even after the antibiotics finish. But don't assume either way. For me, the c. diff. caused my Crohn's to flare before I started on Remicade and was just on Asacol and Imuran.
Good luck! Let us know what happens!
