For the past few days i have had this feeling of a burp stuck in my chest, but nothing ever comes out, unless i try to force it, then i puke a little?

Stuck burp: That sounds like you're describing a really bad spell of stomach acid washing up into your throat (gastroesophogeal reflux, or gerd). The symptoms can get pretty bad, especially if you have a lot of acid all the time (and in some cases, people don't even feel the acid until it's really bad like this). It really should be checked out by your doctor right away. I'd suggest you give them a call.

Reflux?: It could be esophageal reflux. You may want to try Prilosec or prevacid (lansoprazole).
