I don't know if this is colitis, and I have several symptoms that seem to occur together, but it makes no sense to me (as far as what it could mean). I have this bloating going on, way high up right underneath my chest. I also have a stabbing pain that comes with it, in my lower right abdomen, right around where I think my appendix are. I have ruled out appendicitis, because it comes & goes and has been goin on for about a month. I also have explosive diahrea every morning, but then that goes away. A little later in the day I start feeling bloated, then the stabbing pain comes. If I push on the spot where the stabbing pain is, it goes away for a while. Also, if I sit down for a while it goes away. It seems like the more I move around, the worse it hurts. Any ideas?
