Aaron's sign
Referred pain in the epigastrium indicative of appendicitis

Aaron's sign is a referred pain felt in the epigastrium upon continuous firm pressure over McBurney's point.[1] It is a non-specific sign of appendicitis. While the sign is well known, and taught in medical education, its efficacy has not been well established.[2]
