If you do have LPR it is an ENT issue. While waiting to find a responsive doctor, you can read the web site of ENT Dr. Jamie Koufman on LPR and acid reflux. She has good explanations and actionable advice. She had a video this past Wednesday on her FB page in which she said that LPR is a lifestyle condition, and you need to make lifestyle changes to address it. She gave a multi-step detox program in that feed. So look her up on the web and FB and see if what she says makes sense for you. You can also join the acid watchers warriors FB group; they have a ton of low-acid recipes. you can also look up the advice of Dr. Aviv, who also wrote a book on LPR, as did Koufman. Good luck!
