What causes leg cramps? 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.
