I have diverticulosis. Colonoscopy was fine. I never know cramps will happen... just like being in labor. I’ll go to bathroom sometimes solid then cramps worse and end with diarrhea. This lasts hour to five hours. Sometimes can’t make to bathroom. I wear pads to help. 2013 had rectal prolapse surgery. I’ve had colonoscopy and stomach X-rays which are fine. I can feel fine and then bam I start cramping. It’s getting more frequent but I never know when. Afraid to go on vacation or anything
