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]
Aaron's sign is named for Charles Dettie Aaron, an American gastroenterologist. [3]
