In the last 15 years, I've had about 10 butt-scopes, and about 20 upper scopes. I have barrett's esophagus, and it requires constant check-ups/scopes. I have to schedule a follow-up upper-scope on Monday. All the pain-killers and antibiotics tore me up after my back surgery/infection, this past summer. I'm probably due for a butt-scope, also.
I had the camera up the dick to my bladder, about 10 years ago. That was uncomfortable and humiliating. I had to lay there with a white paper-tablecloth with a hole for your dick, while a room full of women [DR included] came and went and made small-talk. The DR took one of those wooden q-tips with some numbing-agent...and told me this won't hurt. WRONG!! She shoved that ****** up my dick, and said it was to make the procedure easier to start. Then she shoved a camera that had a water-hose on it, gradually up to my bladder. Take the worst you've ever had to piss, and multiply it by 10-20X. The water expands and lubricates....but can't escape past the camera. Meanwhile.......my schlong is is standing up from the tablecloth with a garden-hose in it, and the women are chit-chatting. UGH!
