Any medical professionals here? I have horrible right upper quadrant pain?

Did you have any tests to check your small or large bowel? Just wondering if it could be intestinal, especially as you now have diarrhea. It may even be something as simple as irritable bowel syndrome. The ultrasound should have been sufficient to exclude gallbladder and liver disease. I'd go back to get them to recheck things. Maybe barium tests or MRI could help. Best of luck.
