What is restless legs syndrome?
Approximately 10% of the population is affected by restless legs syndrome (RLS), a neurological disorder characterized by unpleasant sensations in the legs usually in the evening or late at night when at rest.

Instead, the team recommends that physicians may need to rotate some patients through different types of medications.
