Exertion

• Sports, fitness routines or anything that overworks the leg muscle can cause leg cramps. Leg cramps from exertion will usually remedy themselves after the muscle is rested. Stretching after a period of intense physical activity may help prevent leg cramps.
  
  

Dehydration

• A common cause of leg cramps is dehydration. A lack of fluids can cause leg muscles to contract and spasm, resulting in painful cramping.
  
  

Dietary Deficiency

• People whose diets lack potassium and sodium may have leg cramps. Eating a well-balanced, potassium-rich diet will often alleviate the problem.
  
  

Massage or Stretch Treatment

• Massaging the leg cramps may help remedy the problem. Gently stretching the leg and flexing the foot will often relieve leg cramps.
  
  

Hot and Cold Compresses

• Using hot compresses to heat and relax the muscle may stop the cramping. If there is soreness after the cramps subside, ice packs may be used to relieve pain.
  
  

Warning

• Individuals with severe leg cramps that appear without warning or obvious cause should speak with their doctor to rule out possible underlying conditions, such as nerve damage or torn muscles.
