Sorry that your having a tough time.
I have been experiencing the same as you. I have a Stricture (Narrowing) near my rectum area.
I have a colonoscopy on Friday and have a corectal surgeon coming in to stretch the stricture while I'm knocked out.
I agree with Fallcolors : Laxatives give me cramps, too rough on your stomach.
On advice of my DR, was told to take stool softeners. (Dulcolax).
They take longer to work but are more gentle on your stomach which should help the pain/cramps.
Hope you feel better soon.
