You'll be OK, Soccer mom. I had one last month and it is not a big deal when compared to the colonoscopy, which is much more invasive. You should not be in any pain, just discomfort, like you really have to move your bowels. And it only lasts a few minutes. You might want to hang around a little while after the proceedure--because the intestine is shaped a little like an accordion, they have to inflate it a little to get a good look, and all that air has to go somewhere eventually.I was really nervous too, but you'll be OK!
