Restless legs syndrome is characterized by an irresistible urge to move the legs and unpleasant tingling, burning, prickling or aching sensations in the leg muscles.
The symptoms tend to come on at night and can interrupt sleep. They may also be triggered by prolonged sitting.
The cause is unknown. Mild cases may be alleviated by self-help measures, such as cooling or warming the legs, walking around, or relaxation exercises.
More severe cases may be treated with medication, such as the anti-Parkinson drug levodopa or anticonvulsants
