Ok i have had crohns disease for about 8 or 9 years now, today i had a colonoscopy aand everything low checked out ok (started remicade several months ago) but everytime i have to have a bowel movement, i HAVE to go right away. If i attempt to hold it at all i will have excruciating lower abdominal pain/spasms. No test seems to give me answers im stumped, anybody else been through anything like that? Because this is new to me
