I recently had a hida scan. The ejection fraction was 19%. My doctor referred me to a surgeon. While doing the scan, they could not get the tracer to show up in the small intestine, so after 45 minutes, proceeded with the cck injection. I had some nausea and cramping. Since the test, I feel extremely tired, and very bloated. I have very little appetite. My family has a history of gallbladder problems and cancer. Should I be worried?
