1 Almost everyone experiences a muscle cramp at some time in their life. 2  There are a variety of types and causes of muscle cramps. 3  Numerous medicines can cause muscle cramps. 4  Most muscle cramps can be stopped if the muscle can be stretched.
Leg cramps can occur for no apparent reason, known as idiopathic leg cramps, or as a symptom or complication of a health condition, known as secondary leg cramps. During a cramp, your muscles suddenly contract (shorten), causing pain in your leg. This is known as a spasm, and you cannot control the affected muscle. The cramp can last from a few seconds to 10 minutes. When the spasm passes, you will be able to control the affected muscle again.
