Some serious TMI here! These are actual shots from my upper G.I. endoscopy. The image at the bottom right is a half centimeter nodule in my esophagus (it was removed). The top center is the most hideous to me, perhaps because I know it most represents the discomfort I feel (the top left is likely to be as well in that the doctor referred to it as "irregular").
A few biopsies and tests for bacteria in progress, results in about a week.
Most interesting part of the experience was propofol, or as I refer to it, the Michael Jackson drug.
