Hi there, have you tried any antacids such as rennies, gaviscon or tums? It sounds like acid reflux or indigestion is what is making you burp like that and have the feeling in the back of your throat. I would suggest taking some antacids and trying to eat normally but possibly avoid citrus such as oranges or other citrus fruits or fruit juices and acid things like vinegar. It sounds like you'll be fine and trying this should bring improvement. Hope it helps
