and not have any symptoms at all? My son, age 2, has an esophageal stricture and they are trying to figure out what caused it. Reflux is something that can cause your esophagus to close up like this. He has never shown any symptoms of having reflux. At least that I have noticed. I am wondering if he could have been having stomach acid spalshing up into his esophagus for the past 2 years but maybe not high enough to feel any reflux symptoms. I am really stretching for answeres as this has been a LONG road. Any ideas are welcome! Thnks in advance. This is a great place for support!
