I have a history of Crohns / Ileitis but I don’t think is that related.I am in a flare-up situation. I also now have INTERNAL hemorrhoids. Whenever I eat most food, within minutes I get rectal urgency. Then I go to the bathroom with diarrhea in a small amount. Then I go again with diarrhea in a small amount.Also, if I eat something and don’t get a reaction… and then go work on the computer, I get immediate tenesmus and rectal urgency. Is it possible to have a food reaction right away like this? What info , causes, or resources can you provide?
