Suggest Treatment For Throat Discomfort

Hello.
I have been having a specific throat problem that has been bothering me for about 2 years and is now really getting worse. It is kind of hard to describe but I shall try my best. So whats wrong is that part of my throat I can move myself and it makes myself burp or push the gas back down but after i do it once i have to do it several times or i will begin to have trouble breathing and sometimes throw up. Also even when i dont make it move by myself that area will feel weird sometimes and then if i dont make myself burp (and sometimes even when i do make myself burp) I will throw up. Its been getting worse and is now happening everyday or twice everyday. Please help I know something is wrong with my throat.
