Sleep related leg cramps are sudden and intense feelings of pain in the leg or foot. The pain is caused when a muscle contracts and tightens. The cramps occur without you being able to control them. They may happen while you are still awake or after you are asleep. They normally begin very suddenly.
A mineral deficiency of calcium and/or magnesium is probably the most frequent cause of night leg cramping. Cramps are often caused by a lack of potassium, resulting in an electrytic imbalance. Strenuous exercise with sweating and diarrhea or other bowel disease may cause loss of potassium and other important minerals.
