The guy was HUGE could that have something to do with it??? Today feel cramps everywhere too

It could be totally unrelated. I had a similar situation, turned out that something I'd eaten (yes, for real) had slightly torn the lining in my bowel, near the anus, and that was causing a slight bleeding. Does it hurt to go to the bathroom now? I'd go check it out with a Dr if I were you, to be on the safe side.
