Leg cramps are sudden and painful. They often occur when the body is at rest, typically during sleep. The muscle cramps can last for a few seconds or up to several minutes. Leg cramps, commonly referred to as charley horses, occur when muscles in the legs contract involuntarily. Muscle groups that mostly involved in leg cramps are calf (back of the lower leg), hamstrings (back of the thigh) and quadriceps (front of the thigh). Some people experience cramps even in their feet, sometimes on their toes.
