Look up schatzki's ring. This could be what you all are experiencing. It is not often diagnosed in the US but can cause many problems. I found it while trying to learn why I can never burp. Hope it helps!
i am going through this and have seen every kind of doctor and tests and still unknown how to control. next up is a endoscopy as all tests have come out ok. good luck get back to me on update.
Hi I'm Angela! I'm having the exact same problem. Going on for 5 or 6 yrs. On & off. My doc. said it's acid reflex. I had no heart burning. After taking meds for acid reflex for 3yrs. Now he's saying I don't have acid reflex. I recently had 2 full physicals. He told me I was in good health, no respiratory problems. I'm going for a 2nd opinion asap. When I'm coughing and choking I feel so embarrass. At times i don't want to eat.
Gustatory rhinitis - have had it since I was a kid (now 45).
