Rebound tenderness (also called the Blumberg Sign) is a nonspecific clinical sign that a doctor may detect when examining the abdomen.  It refers to pain or tenderness that occurs upon sudden release of pressure on the abdomen. It may be a sign of inflammation or infection of the peritoneum (that is, the inside lining of the abdomen) that may indicate peritonitis. It may be seen with appendicitis (inflammation of the appendix), colitis (inflammation of the colon), etc… 

Rebound tenderness is a symptom of many diseases, including appendicitis. It can also indicate a twisted fallopian tube, hepatitis, a strangulated hernia or diverticular disease or a strangulated hernia. Doctors use tests to determine the cause of rebound pain.
