Hi! I have a question. How do I know if I have just long-term acid reflux or the actual diagnosis of GERD? My GI doc put me on omeprazole, (literally doing nothing after two weeks), but didnt give me a firm diagnosis yet. I've never had acid reflux problems before (I have had other GI issues), but this has been a new problem for the last two months. I've had daily heartburn on and off all day, consistent sore throats/raw-feeling throat, bad taste in my mouth and unusual bad breath, upset stomach and horrible nausea (especially near the top of my stomach), etc. Ideas?
