Clinical Classification

Clinical Information

  • Tetany

    a disorder characterized by muscle twitches, cramps, and carpopedal spasm, and when severe, laryngospasm and seizures. this condition is associated with unstable depolarization of axonal membranes, primarily in the peripheral nervous system. tetany usually results from hypocalcemia or reduced serum levels of magnesium that may be associated with hyperventilation; hypoparathyroidism; rickets; uremia; or other conditions. (from adams et al., principles of neurology, 6th ed, p1490)

Muscle Cramps

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
  • Pregnancy
  • Certain medicines
  • Getting dialysis

Sometimes the cause of muscle cramps is unknown.

Who is at risk for muscle cramps?

Anyone can get muscle cramps, but they are more common in some people:

  • Older adults
  • People who are overweight
  • Athletes
  • Pregnant women
  • People with certain medical conditions, such as thyroid and nerve disorders

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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
