I don't know if anyone has had the same thing happen to them but in the morning usually I don't feel as though I'm 100% until late morning or after lunch. I've had ongoing digestive issues for over a year now. Recently I've been having acid reflux and pain in my chest area expescially when I exert myself. In the mornings I experience a nervous type feeling in my stomach, kind of short of breath, and lightheaded sometimes. I've had so many tests done in the last year such as 2 different types of stress test, heart scans, 2 stomach ultrasounds, a colonoscopy, endoscopy, barrium swallow test, gastric emptying survey, probably 4-5 blood test have been run also. Everything has been pretty much normal. Just kind of lost on what to do next. Doctors look at me and think everything is in my head since the test have been normal. Any clues ?
