Good luck. I have achalasia (narrow esophagus). It was a problem for about 7 years, so had a bunch of endoscopies, gastroscopies, and sometimes while they had me under did colonoscopies for laughs. I was groggy the rest of the afternoon from the anathesia, but was always fine the next day to run or whatever.

So you were the butt of their jokes?  Sad, very sad...
