As the title suggests, I'm having a sigmoidoscopy in a bit over a weeks time (having a enema before which I have to do at home.....). Has anyone had one? What did you have it for? What was it like? How long did it take them to get the results back to you? And how was it baring your butt for all to see? (should have gotten over the embarassment thing after giving birth, especially with stirrups used ) Thanks!
