I get it too only when I drink. Are you drinking anything carbonated? That might be it.

Just try to burp it out. Whats the worst that can happen? You'll throw up maybe? That will make you feel better either way so trying to get it out is a win win. I'm not sure what it is I think it's just gas stuck in your windpipe or trachea. It takes a little effort to get it out.
