'''Kehr's sign''' is the occurrence of acute pain in the tip of the shoulder due to the presence of blood or other irritants in the [[peritoneal cavity]] when a person is lying down and the legs are elevated. Kehr's sign in the left shoulder is considered a classical symptom of a ruptured [[spleen]]. May result from diaphragmatic or peridiaphragmatic lesions, renal calculi, splenic injury or ectopic pregnancy.
Kehr's sign is a classical example of [[referred pain]]: irritation of the [[Diaphragm (anatomy)|diaphragm]] is signalled by the [[phrenic nerve]] as pain in the area above the [[collarbone]].
The discovery of this is often attributed to a German [[gall bladder]] surgeon named [[Hans Kehr]], but extensive studies into research he conducted during his life shows inconclusive evidence as to whether or not he actually discovered it.<ref>{{cite journal | author = Klimpel V | title = Does Kehr's sign derive from Hans Kehr?
