Rovsing's sign, named after the Danish surgeon Niels Thorkild Rovsing (1862–1927), is a sign of appendicitis. If palpation of the left lower quadrant of a person's abdomen increases the pain felt in the right lower quadrant, the patient is said to have a positive Rovsing's sign and may have appendicitis.
Can this go hand and hand with the pain felt around the umbilicus or is it that the pt can feel one or the other?
The sensitivity of Rovsing sign in various studies ranges from 19% to 75% with a specificity of 58% to 93%.
