Well, your symptoms seem to be very similar to mine. Except I seem to have some shortness of breath (I think because of the fullness/bloating). I just had an endoscopy, and they found bile in my stomach - as well as gastritis. I'm not sure if thats my "offical" dx... but it sounds like it.
I'm on Nexium, which virtually eliminates the pain and burning... but the bloating, upper abdominal fullness, and IBS type symptoms are unchanged.
