Hello. I have been having this sensation of air stuck in my throat and chest. It started roughly 3 weeks ago. I ended up with what I think was Viral Gastroenteritis and since then the symptoms slowly started and now are quite bothersome. I feel like I have an air bubble ( for lack of any other way to describe it) stuck in my throat and chest. It s like swallowing too much air , but this has gone on now for the last few weeks. I ve also developed a dry cough in the last 5 days, that seems to be increasing daily, along with my symptoms. Is it possible from throwing up so violently from the virus, that my Esophageal sphincter is stuck open and hence I have air coming up from my stomach or when I swallow that is trapped and causing these symptoms? My chest feels tight and I can t seem to get a deep enough breathe or enough air in when I inhale.
