Actually, I was referred to an ENT who specializes in voice/rare throat disorders. Most of his patients are cancer patients and pre-cancer patients (according to him, if silent GERD goes left untreated can develop into esophageal/throat cancer). He said that acids can flow up into your sinus cavities and ears. I had severe ear pain and have actually lost some hearing in my left ear. When I see local GP or even local ENT, they see nothing in my ears. Sometimes they see fluid, but cannot tell if it is draining from sinuses or from acid refluxing upward. I even went so far as to have sinus surgery last summer to try to improve things. Guess what? After surgery, my GERD got worse! So, it confirmed that the sinuses were not the problem. I am scheduled to have Nissens Fundoplication on Tuesday so I hope to finally get some relief from all of these symptoms! It can be dangerous. Acid can also back into your lungs. Acid Reflux is not just something that overweight people get from poor eating choices. It can be very serious! AND, not enough doctors are aware of these atypical symptoms that seem unrelated. I have had to convince my own GI that there is a relationship between the two. Between my cancer specialist and myself, we finally have my GI doc onboard. And, I am finally able to try to get some relief with the fundo....wish me luck and good luck to all of you! If you have chronic sinisitis, which is what will end up happening, check into it! It is very possible that it is your GERD.
