I had the same exact thing for 15 years, and went to so many Doctors I lost count.
When you open your mouth and look in the mirror and see the back of your throat, I had two slits or crevasses about 1/3 to 1/2 of an inch deep that would collect food and it would rot (sorry for being graphic) when your throat swells the food is pushed out, and the cycle begins again. When I was showed what and where it was, I broke off an arm from a pair of old glasses I have, pushed it around the back of my throat and it went right into the slit pushing out the food. I did not want to do this the rest of my life so they laserd my throat down to the point where I would not have a crevass anymore.
This is rare so many Doctors do not know about it. Sick as a dog I was for years.
I had Dr. Flick
In Waukesha, Wisconsin
At Aurora
I think I am spelling Aurora right?
Call them for information and please pursue what I said, I believe you will be gratefull.
