I'm a little concerned that you said this is happening all of a sudden even though your heartburn is gone. I have the throat soreness but its only after years of having the acid reflux. It started way before I even knew what GERD was. I read your other post as well about
your tongue swelling up... are you on any other medications that you started taking recently? I would check this out with a doctor and please keep us posted.
