Are you talking about a Cystoscopy? b/c that is what i had done in the dr's office..he inserted a camers to look at the wall of my bladder,,(,he also filled it with water) it was inflamed & turns out i have Cystitis.
Yes it was worth having it done b/c at least NOW i know whats is wrong..I am taking Elmiron for it.
I had NO pian relief & he said the numbing gel was USELESS,,so none of that as well. it stung a bit, but the test was less than 5 minutes, & it stung the next few times i pee'd.but i was fine the next day.
Good luck to you~~~
