Nighttime leg cramps are a sudden intense pain in the thigh or calf. A cramp is a tight muscle that won't relax. They can be caused by mineral deficiency.
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.
