I researched everything that could cause sob. My symptpms somewhat matched esophageal and throat conditions. Therefore I thought I might have the gerd causing issues along with possible stenosis of the throat due to being intubated so many times. I still might be right on the gerd irritating the esophagus. I'm losing confidence in my Gastrointerology people. They can't get their diagnosis pr reports right. Even my pulmonologist and the ENT specialist seem perplexed by their clinical impression. Anyway, the ENT guy seems to be on top of things for now. I'll stick with him for sure but may switch to another gastro specialist.
