I had gerds for almost a year before the new symptom of plugged up ears surfaced. I have done research and have read alot of other forums, and yes....plugged ears, pain in ears, ringing in ears...all are symptoms of LPR. LPR (larypharyngeal reflux) is when the acid sits in your throat. While gerds affects mainly the esophagus, lpr affects the throat. There are two sphincters in the esophagus, one at the bottom near the stomach (lower sphincter) and one on top near the throat (upper sphincter). When someone has LPR, the upper sphincter does not work properly, hence the acid in the throat...Other symptoms are hourse throat, burning throat, problems swallowing, post nasal drip, and nagging cough. You can have gerds without lpr, and you can have lpr symptoms wihout the burning heartburn that we associate with gerds, or you can have both....Ears, nose, and throat are all anatomically connected so it stands to reason that the acid can and often does affect all of them.
I hope this helps!
