Q

Impt hx questions you should ask your pt about abdominal pain?

A
  • the way the pain begins: if pain comes on suddenly it suggests sudden event like ischemia or biliary colic
  • location of the pain: diverticulitis: LLQ, Appendicitis: RLQ

Pancreatitis: severe, unrelenting, steady pain in upper abdomen and back. Acute appendicitis: starts near umbillicus, and moves to RLQ
