It sounds just like all of us in a group I’ve followed and posted in a number of times, ‘Phlegm in My Throat and Post Nasal Drip’. August 2022 for me. I know I resisted a gastroenterology cause but now being on Famotodine 40mg twice daily I’m feeling some relief. This after rounds with pulmonary - Albuterol and Symbicort, few findings with ENT (how about speech therapy!) and a year of self treatment (chewing gum worked the best). I’m scheduled with gastroenterology in February 2024. So frustrating but mine had moved into constant chest pain and Famotodine has improved that and the gagging phlegm is relieved tremendously. I never thought it could have been Gastro either be since I didn’t experience heartburn but I do think this is it.
