A week ago, out of the blue I started to excessively throat burp. If I open my mouth no burp would come out, but once I close it, I burp up a storm, I only get maybe a minute of relief before it happens again and this is all day and night. I have acid reflux, hiatal hernia, gastroparesis and esophagus spams and I have been on dexilant 60 mg for a few years now. What could have caused this sudden excessive throat bleching and how can I get it to stop?
