A muscle cramp is often called a charley horse. It is an uncontrolled contraction of the muscle and produces intense pain. Muscle cramps most often occur in the calf or foot. They can also develop in other areas of the body. Muscle cramps usually happen while lying in bed or playing sports or exercising. Overuse, injury, muscle strain, or staying in the same position for a long time can produce cramping.

Night time calf cramps usually strike a person when in bed. It is possible that the day's activities such as a tough workout, wearing high heels, or taking some drugs (diuretics) may spark the cramp. Pointing the toes sharply can instantly cause cramping.

Cramps during exercise can be prompted by a number of factors. Dehydration or sweating too much can create an imbalance in electrolytes (potassium and sodium) in the blood. Overexertion or muscle fatigue are common causes as well.

For relief of a muscle cramp try ANY of the following:
* Stretch the muscle by straightening the leg and flex your foot upward.
* Massage the muscle to relax it.
* Apply a cold pack to reduce the blood flow and relax the muscle.
* Take a hot bath or use a heating pad for relief.

To prevent muscle cramps:
* Do stretching exercises before and after workouts.
* Stay hydrated--drink plenty of water.
* Drink water or a sports drink if the cramp attacks during a workout.
* Do not over-fatigue muscles.
* Do not point your toes while stretching or sleeping.
