So when I was having problems breathing thru my nose and went to my primary care doc, and we it was assumed was a chronic sinus issue, she sent me to see ENT who is suppose to be a sinus specialist. I have had GERD for many years, but had it under control, and was pleased for that. But ENT doc looked at my sinus x-rays which said that my sinuses were narrowed and almost completely occluded, and his statement was that "he was not impressed" . He did not even do any exam. He handed me a brochure on Laryngeal,Pharangeal,Silent Reflux and said this is a GI problem. Go back to GI. So I did. Evidently ENT says that refux from your gut comes up and can go all the way up into your sinuses causing occlusion. My GI docs act like there is no such diagnosis. They just keep wantin to increase the dose of the PPI. If you google LPR you can read what the term means, and it does not sound to me that all medical people are in agreement with the Dx.
