About Muscle Cramps (the broader symptom)

What are muscle cramps?

Muscle cramps are sudden, involuntary contractions or spasms in one or more of your muscles. They are very common and often occur after exercise. Some people get muscle cramps, especially leg cramps, at night. They can be painful, and they may last a few seconds to several minutes.

You can have a cramp in any muscle, but they happen most often in the:

Thighs

Feet

Hands

Arms

Abdomen

Area along your ribcage

What causes muscle cramps?

Causes of muscle cramps include:

Straining or overusing a muscle. This is the most common cause.

Compression of your nerves, from problems such as a spinal cord injury or a pinched nerve in the neck or back

Dehydration

Low levels of electrolytes such as magnesium, potassium, or calcium

Not enough blood getting to your muscles

Sometimes the cause of muscle cramps is unknown.

Who is at risk for muscle cramps?

When do I need to see a health care provider for muscle cramps?

Muscle cramps are usually harmless, and they go away after a few minutes. But you should contact your health care provider if the cramps:

Are severe

Happen frequently

Don't get better with stretching and drinking enough fluids

Last a long time

Are accompanied by swelling, redness, or a feeling of warmth

Are accompanied by muscle weakness

What are the treatments for muscle cramps?

You usually don't need treatment for muscle cramps. You may be able to find some relief from cramps by:

Stretching or gently massaging the muscle

Applying heat when the muscle is tight and ice when the muscle is sore

Getting more fluids if you are dehydrated

If another medical problem is causing the cramps, treating that problem will likely help. There are medicines that providers sometimes prescribe to prevent cramps, but they are not always effective and may cause side effects. Talk to your provider about the risks and benefits of medicines.

Can muscle cramps be prevented?

To prevent muscle cramps, you can:

Stretch your muscles, especially before exercising. If you often get leg cramps at night, stretch your leg muscles before bed.

Drink plenty of liquids. If you do intense exercise or exercise in the heat, sports drinks can help you replace electrolytes.
