The term Charley horse is a popular Americanism for leg pain caused by a thigh contusion involving the quadriceps muscle. Without immediate compression, the ensuing haematoma and pain can be substantial. The term may refer to painful injuries of other muscle groups.
Management Massage foot in direction opposite of spasm; ingest bananas (for potassium). Some believe that beating the spasming muscles with their fist helps.
The origin of this phrase for muscle stiffness is unknown; it is anecdotally related to a horse named Charley who walked with a limp, drawing a roller to flatten the playing field in the Chicago White Sox baseball park during the 1890s.
Synonyms Charleyhorse, corked leg, corky, dead leg
