Gas bubble in throat i can swallow water but food has a little trouble going down but it does goes down after i drink bubble feel trying to come up?

This would fall into: the category of GERD: gastroesophageal reflux disease. Often folks experience liquid reflux, but it can just be air/"a bubble". GERD typically related to/caused by incompetent lower gastroesophageal sphincter...the valve between the esophagus and stomach. I see you are already taking pantoprazole and ondansetron...medications typically used for GERD. Continue to work with your treating physician.
