Brief description

This is a neurological disorder which manifests with an often unpleasant or uncomfortable urge to move the legs, during periods of inactivity.  It is most prominent in the evening, and is transiently relieved by movement.  There are often associated, characteristic limb movements during sleep.

This is a separate disorder from periodic limb movement disorder, which is covered by separate SOPs.

The appropriate medical specialist is a neurologist.

Clinical onset
