I've never been backed up for several days, but I do feel at times like I have waste that needs to come out but it can't GET out. It is like there is a kink in there, or a gas pocket that has blocked traffic. I have found that sometimes sitting on the toilet and stretching upward and sometimes massaging my abdomen with small, firm circles can help get things moving.
If I am having 'trouble' it is not unusual to spend 10min or more sitting on the toilet to be sure everything has evacuated. I seem to only be able to eliminate in small portions when my stool is very loose and it takes about 10min for everything to travel out. Otherwise, I am up/down/back/forth on the pot because I didn't give everything time to evacuate. When stools are firmer, they are usually able to evacuate in one large sitting, though I will still sit for 5-10min to be sure I am done. I really HATE going to the bathroom, so I don't want to be gong back/forth and would rather get it all out at one sitting.
Anyway, try the stretching and deep massaging to stimulate your bowels to move, see if that helps.
I have the ability of single-minded determination and accurate project focu....Hey, look, a cat!
Crohn's and UC are pretty darn crappy, but if you can't laugh at yourself, you'll cry......I'd much rather laugh.
2001 Dx'd with UC. No remission. No improvement with Remicade. 5/2008 surgery, removal of 6" of left side colon. Dx changed to Crohn's. Remission for 8-9wks after surgery, symptoms returned after resuming 6MP. Changed maintenance med to Methotrexate (MTX) and had great results with IM injections. Nausea and symptoms returning with oral MTX. Switched back to IM injections and am slowly improving.
