I'm so glad I found your comment. I have been experiencing the exact same symptoms for almost two weeks and the doctors cannot determine what is wrong. The pain at times is excruciating, while other times it's not as bad but it is always there in the exact same location you described. I had my appendix removed years ago. I was originally sent to ER, have since seen my doctor twice and now am being referred to a gastrointestinal specialist. I've also had multiple tests and am scheduled for a PIPIDA Scan next week. I just want the pain, indigestion, diarrhea and acie reflux to go away! I can't eat anything because everything send me to the bathroom and makes me nauseous. Very frustrating! I'm hoping the PIPIDA scan will reveal something.
It could be your appendix or your pancreas(spelling?).
