A leg cramp is a sudden, uncontrolled contraction of a muscle. This type of pain is most commonly experienced in the lower extremity, and therefore often called a leg cramp or a charley horse.. Leg cramps occur when the muscle suddenly and forcefully contracts. The most common muscles to contract in this manner are muscles that cross two joints. These muscles include the calf (crossing the ankle and knee), the hamstring (crossing the knee and hip), and the quadriceps (also crossing the knee and hip).
