Gall bladder disease is most likely in north america - but the possible causes are huge.
I usually like to clear up emergency conditions. I also divide into systems. But the main ones are atypical heart attack, hole in the lung, blood clot in the lungs, pneumonia, pancreatitis, hole in the stomach, appendicitis etc etc. I have seen gonorrhea present as right upper quadrant pain.
Would you like to video or text chat with me?
