I have nausea and upper abdominal pain especially after I eat. Since mid 2000 I have had fecal tests colonosopy Endoscopy(x2) Abdominal ct scan, Upper Gi(x2 over a year)blood bee diagnosed with work and numerous ultrasounds. The only thing I have is Gerd and 2 duodenal ulcers which were caused by h pylori and have been eradicated. I had a second endoscope 3 months ago which was all clear. I hate the pain and especially the nausea so I can sympathize, good luck!
