Leg cramps are most common in the calf muscle, but they can also happen in the thighs or feet. Muscle cramps happen when a muscle involuntarily contracts on its own. Cramps usually occur for a reason. If a muscle is not strained, cramping is occurring because the muscle is fatigued or overused, or the body is dehydrated. Sometimes, cramps might be related to alcoholism, hypothyroidism, or diabetes. Generally, the effects of a leg cramp will disappear in minutes. But with ongoing leg cramps, speak with a doctor.
