acid reflux is probably what you have also a hienal hernia big gases from your stomach keeps this from closing your food maybe coming back up especially if you bend over do do work or exercise if food is getting stuck in your throat see a doctor. I just found out that I had a bonespur in my throat that keeps me from swallowing pills so go see a doctor
It could be anything from a mild case of upset stomach to a serious medical problem. Only a medical assessment can tell which is the case for you. Food stuck in the throat is particularly worrying and is potentially life threatening particularly, if it results in a foreign body airway obstruction. You should consult a physician to play it safe. Good luck.
I had a friend with acid reflux that caused the same symptom with food and it was his dooadium. That is not proper spelling but it is a flap of some sort. he waited and had to have minor surgery that could have been avoided all together.
