I have been having a fluttering sensation under my right rib cage, and if i push on my stomach right under my sternum, the stomach is very sensative to the touch. I have been having constant diarrhea and stomach pain about 10-20mins after eating. Doesn't matter what it is that I eat but mostly foods that are fatty seems to be worse. Anyone have any thoughts as to what this might be? Oh, I've had a hida scan done with an injection fraction of 27% about 4months ago and another about a year ago and that was 26%.
