Sorry if the subject of this thread in gross, but I couldn't think of a better way to phrase it. Anyways, twice today I have had diarrhea with foam in it. The entire bowl wasn't foamy or anything, just a couple relitivly small areas. I have also felt a bit gassy as well. Mabye I;m just being a hypochondriac but I just found it a bit strange. Could the foam just be gas, or is it something I sohuld be worried about?
