. It will "refer" pain often to the mid upper abdomen, the epigastrum. Because the appendix is a piece of intestine, it follows a similar referral pattern. An appendix with some early inflammation may give a non-specific irritation somewhere near the umbilicus (belly button). Should the inflammation become severe, it may actually irritate the inner lining of the abdominal cavity called the

peritoneum The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal (or coelomic) organs, and is composed of a layer of mesotheli ...

. This thin layer of tissue lies deep to the abdominal wall muscles. Now the pain has become "localized". If pressure is applied to the muscles of the right lower abdomen (or

) near a very irritated appendix, then the muscle fibers in that area will be stretched and will hurt.

Process

Pathologic explanation: This maneuver elicits tenderness in the right lower abdomen, because contents of the left lower abdomen are shifted upon application of pressure, further irritating the inflamed peritoneum. A Rovsing's sign is elicited by pushing on the abdomen far away from the appendix in the left lower quadrant. The appendix, in a large majority of people, is located in the right lower quadrant. While this maneuver stretches the entire peritoneal lining, it only causes pain in any location where the peritoneum is irritating the muscle. In the case of appendicitis, the pain is felt in the right lower quadrant despite pressure being placed elsewhere. Most practitioners push on the left lower quadrant to see where the patient complains of pain. If pain is felt in the right lower quadrant, then there may be an inflamed organ or piece of tissue in the right lower quadrant. The appendix is generally the prime suspect, although other pathology can also give a "positive" Rovsing's sign. If left lower quadrant pressure by the examiner leads only to left-sided pain or pain on both the left and right sides, then there may be some other pathologic
