I have been experiencing pain on my right side for over a year, which moved around somewhat and constant mucus in my stool. Now the right side pain has basically left but no I have stabbing pain below my belly button to groin area sometimes. In one day I can go to the bathroom up to 10-20 times, mainly just discharging mucus. On occasion there has been pink mucus or bright red mucus, but not often. I also noticed when I pooped the mucus, sometimes there were bubbles.. I'm taking Bentyl now, but still feeling the stabby pain near my groin.. Any idea, as I was told IBS.. Could it be celiac or something else?
