Causes of Muscle Spasms
Muscle spasms are sudden involuntary contractions of one or more muscles. Muscle cramps can have many possible cause:
- Inadequate blood supply in the legs.
- Overexertion of the calf muscles while exercising.
- Insufficient stretching before exercise.
- Overuse of muscles.
- Insufficient magnesium, calcium, or potassium in your diet.
- Malfunctioning nerves, such as a spinal cord injury.
