I get a feeling as though there is something stuck in my esophagus/throat, and then every now and then I force out a little burp. But then my thoughts take it away to fearing my throat is going to close up etc...., and panic! I know from some internet searching that it can be a symtpom of gastroesophagal reflux disease. Which is a non-worrisom condition with diet and medication, but has anyone else had this? What could this be?
