i have been having pain in the epigastric and under the right rib cage. i've also been having terrible heartburn, nausea and vomiting for about the past month. My liver enzymes are elevated, an ultrasound came back negative for gall stones. My HIDA scan showed an EF of 96%. Is there anything i can do to stop the pain and nausea. It happens every time i eat and it doesn't matter what i eat either i've changed my diet to low fat small meals but the pain is still there.
