Diagnostics

History, clinical examination, laboratory (including Mg electrolytes, kidney / liver function tests, blood sugar, thyroid, CK), venous examination.

 

Therapy

Depending on the cause, for example,

In the acute stage: break with activity, cold ice, compression stockings, high position.

To solve the acute spasm should shorten the muscle, and then tighten the antagonist (countermovement), because this inhibits the cramping muscle over a nerve strang in the spinal cord. A massage of the affected muscle often helps against the pain as well as showers with hot and cold water.

 

Other preparations, such as magnesium, theophylline, quinine, phenytoin, Ca, Vit E, compression stockings can be used.

 

Prevention

Prevention of muscle cramps by adequate fluid, intake of magnesium (in foods: nuts, spinach, whole grains).

Warm up before exercise.

Circulation-promoting measures such as exercise, warm-cold baths.

Adequate stretching in sports.

No excessive consumption of alcohol and coffee.
