I seriously recommend that you see an ENT doctor. Please don't put it off any longer.

Just listening to your description of symptoms can give the doctor lots of information, and decide where to go from there. Perhaps Nexium will work for you, or maybe they need to do an endoscopy (a check of your esophagus, with a tiny camera that amplifies the area) to get more information.

I have experienced the endoscopy, you're welcome to PM me if you have any Q's or concerns.
