I don’t have choking or coughing but I do have excessive mucus in my throat especially after eating or drinking. ENT says it is reflux. I am having an EGD and they will attach a capsule to my esophagus and this is the only way to know for sure if it is reflux. Mine has been going on for over ten years. I seriously doubt that I can have LPR for so long without damaging my esophagus. I know a lady whose esophagus was detached from her stomach due to the acid.
