So look up Funtional Despepsia. This is what I was diognost with at the Mayo Clinic in Rochester. I had every test imaginable. They believe everyone with the symptoms bur cannot find a cure. I even checked in Europe and they all say the same thing. It is a condition, but unexplainable. I start a light dose of anti depression meds. I feel bad for you I know how you feel. Just keep searching on your own, unfortunately the medical proffesion is so busy, look for answers and have a medical profession check it out. I asked about Functional Dyspepsia when I first joined this site, and most professionals never heard of it. Takeare stay strong.
