My dad spent, I believe, 3-4 years where every single meal he would gagging on the food and end up throwing up. Initially, they thought it was from the severe and chronic throat infection he had and because of our health care system it took them that many years to get his tonsils removed and at least rectify the infection issue. That didn’t solve the problem though, and eventually it turned out there was damage to a nerve in his throat that was causing it and he needed another surgery to fix that.

Watched him go through hell all those years, so I definitely feel for you and hope you get this resolved!
