I have had my esophagus stretched about three times since my radiation and chemo treatments for tonsil cancer ended in January 2008. The last time was 7/17/09. My gastronterologist performed the procedure, which was called an Upper GI Endoscopy. Mine showed an esophageal stricture, which he dilated. I also had gastritis, for which he prescribed medicine. However, the procedure was very simple and I believe all I had was valium to be sedated. My throat felt a little sore for several hours afterward, and then was fine. I could really tell the difference in swallowing - he told me I should probably have the procedure done about every three months or so. Good Luck with your procedure(s).
