There may also be a gene in those who are older, but this is still being investigated.

The person has uncomfortable sensations in the legs.
Some people feel a pulling sensation, tingling in the legs, or aching in the legs.
The cause is unknown. It usually occurs when one is inactive and often becomes worse during sleep. It can occur by itself or with Parkinson's or possibly with other movement disorders. The same medications are used because they help relieve the symptoms of both disorders. Often techniques as warm baths are used to relieve symptoms.
