I am also having this problem, but I never know when it's going to happen or what foods are going to cause it. I can eat the same thing and it may or may not happen. But I have also noticed that if I can get out a few burps that the food seems to go on down, almost like it is an issue with the food and air trying to change places. I keep asking my doctor's office and they tell me they have never heard of anyone having this before, the doctor just says that I am trying to eat too fast. However, it doesn't seem to matter how slow or how much I chew up the food....sometimes it will get stuck on the first couple of bites!
That is another issue I have......I seem to have gas all the time, especially burping! Is this a common side effect?
