Is There a Difference Between Pain and Abdominal Pain?

Pain in the right upper quadrant has a completely different differential diagnosis than pain in the left lower quadrant. The third issue is the ime course of the pain. For instance, if someone's had pain for ten years, it's not an abdomilarto anerism. It can help to know whether the pain is very discreet in its episodes, or whether it waxes and wanes more gradually.
