I think I have this, but wanted to check to see if anyone else has it and what their symptoms are.
I constantly feel stomach acid bubbling up into my upper esophagus and throat, accompanied by a feeling of a lump in my throat that seems to impede the passage of food, also accompanied by constant post-nasal drip.
I'm seeing a doctor next month for these symptoms, but found a description of Laryngopharyngeal reflux on the web and thought it fit my symptoms. I almost never have heartburn.
There are a lot of people on the acid reflux thread with LPR. It might be worth your while to visit that board. Also, try searching this board for LPR. You should find a lot of helpful information.
