how long has this been going on? if it has been a few weeks, see a dr and get scoped. ask all of the questions that you have based upon your own experience, what you find in this forum, and what you find elsewhere on the internet.
my gerd isn't unusual (i am finding). i have "postnasal drip", problems swallowing, constant burping, and problems swallowing. sound at all familiar?
good luck. keep us posted.
