Lesson: Sounds like you've been through the gamut of testing and while there are numerous other tests that you might endure, I would suggest something simple: don't eat oily meals!! In fact, there may be a few foods that simply don't agree with you and I recommend you pay attention when certain foods cause you symptoms. Also, speak with your doctor about seeing a nutritionist and possibly an allergist.
