Involuntary muscle contractions are familiar to nearly every patient, partly because cramps have several possible precursors. Although muscle cramps do not have any serious long-term medical consequences, they can be uncomfortable and knock an athlete out of a game. The key to treatment and prevention can often be found in the cause.
