23 into your esophagus or throat? Dr. Koufman told me one episode of reflux into the throat is considered to be abnormal. Also, what were you refluxing (acid, non-acid, gas, etc.)?
When my flare-up began, I had post-nasal drip, throat clearing, excessive mucus/globus/pnd, chronic cough, lots of thick and sticky saliva, non-stop belching, and a burning sensation in my nasopharynx cavity every morning upon waking. I also had my first and major flare-up in 2009, in which I also experienced food sticking in my throat.
Since you didn't respond to PPI's, I wonder if you have ever been tested for neuropathy, as sometimes burning is one of the only symptoms of this.
Thank you for the warm wishes, I also wish you a fast and speedy recovery.
