Leg cramps at night are most frequently caused by calf muscles, although they may also develop in the foot or thighs. To reduce the pain, the stiff muscle must be extended.

The gastrocnemius (calf) muscle, which runs the length of each leg from ankle to just below the knee, is a common cause of leg cramps. They may, however, impact the muscles at the front of the thigh (quadriceps) and the rear of the thigh (tibialis posterior) as well (hamstrings).

Leg or calf cramps at night strike women and the elderly more often than any other age group.

Leg cramps that occur during the night might be a result of improper foot position. Plantar flexion is a frequent sleeping position in which the feet and toes are stretched away from the rest of the other body.
