Hi Becca! I had to have the endo thing. It was fine. They knocked me out, did it and then woke me up. Simple as that...no pain and I was fine. My surgeon made me have it, who knows why, I just did what they said to do, oh the hoops.......and I have not ever had banding or anything. All my info was submitted to ins compay and now I wait and wait and wait. Good luck to you and do not be fearful of the test. Its really nothing to worry about. Take care and best of luck! Vicki
