Definition
A muscle cramp or "charley horse" is a painful, involuntary muscle contraction. Muscle cramps are also called muscle spasms.
What are the signs and symptoms of the condition?
The main symptom of a muscle cramp or spasm is pain in the muscle. The muscle itself is tender to the touch. In most cases a person is unable to continue using the affected muscle due to the pain.
What are the causes and risks of the condition?
The exact cause of muscle cramps is not well understood. They can occur in any muscle at any time. Cramps occur most often in the muscles of the leg or foot. They usually occur while playing sports, exercising, or lying in bed. The calf muscle in the back of the lower leg is a common place for nighttime cramps. These often occur after vigorous exercise.
Tight muscles are more likely to cramp than flexible muscles that have been stretched. A low level of physical fitness increases the risk of muscle cramps. Overexertion and muscle fatigue also contribute to cramping. Excess sweating or dehydration can deplete
minerals in the body. These minerals are important for good muscle function and include sodium, potassium, calcium, magnesium, and phosphorus. Medications like diuretics or water pills can also lead to cramping due to loss of sodium and potassium.
Other situations can contribute to muscle cramping.
- A person with one leg longer than the other is more likely to develop cramps.
- People who run with too much rolling in of the foot or too much rolling out of the foot, are more likely to get leg cramps.
- Wearing high heel shoes can also cause cramping.
- A poor blood supply to leg muscles caused by smoking and atherosclerosis (hardening of the arteries) can cause a type of calf pain called claudication.
The common muscle cramp lasts a few seconds to minutes. It does not carry any risk of other long-term medical problems.
What can be done to prevent the condition?
Stretching the calf and other leg muscles improves flexibility. This reduces the risk of cramps. Individuals who get nighttime calf cramps should:
- sleep on their sides
- sleep with their toes pointed
- not tuck in their blankets and sheets too tightly. This can bend the toes down and cause a cramp.
- eat a diet rich in fruits and vegetables to reduce the risk of mineral deficiencies.
- drink plenty of water before, during and after exercise to prevent dehydration, especially during hot weather
- wear comfortable shoes with good arch support to helps prevent cramps
In the past, salt tablets were recommended to prevent muscle cramps. However, salt tablets are not useful and should be avoided.
