Charlie Horses also known as Muscle spasms . It often occur when a muscle is overused or injured. Things that might bring on a muscle spasm include:

  • Exercising when you have not had enough fluids (you're dehydrated).
  • Having low levels of minerals such as potassium or calcium.

Some spasms occur because the nerve that connects to a muscle is irritated. One example is a herniated disk irritates the spinal nerves and causes pain and spasm in the back muscles.
