muscle cramps information from trusted sources:
A muscle cramp is a sudden and involuntary contraction of one or more of your muscles. Muscle cramps can result in intense pain and leave you temporarily unable to use the affected muscles.
As we normally use our muscles, they alternately contract and relax as we move our limbs back and forth. Similarly, the muscles that maintain our posture contract and relax in a synchronized fashion. A muscle that involuntarily contracts without our consciously willing it is called a "spasm." If the spasm is forceful and sustained, it becomes a cramp. A muscle cramp is an involuntarily and forcibly contracted muscle that does not relax. Muscle cramps cause a visible or palpable hardening of the involved muscle.

Anemia, arthritis, and even arteriosclerosis may result in cramping. Most muscle cramps occur at night when resting and affect the legs, especially the calf muscles, and the feet. These kinds of cramps occur more frequently in the elderly, the young, and persons with arteriosclerosis.
