Restless legs syndrome (RLS) is a common neurological disorder characterised by an irresistible urge to move the lower limbs, often accompanied by unpleasant sensations in the legs, typically occurring in the evening and at night and improving with movement. Restless arms syndrome (RAS) predominantly affects the arms, while the legs are rarely affected. RAS appears to be very rare, with very few cases described to date, but the diagnosis of RAS is probably made too infrequently, especially for milder and transient forms. The patient reported here even had severe symptoms for years that could have indicated RAS. He observed an immediate improvement in all RAS-related symptoms after administration of 100 mg L-dopa +25 mg benserazide, which continues to this day. Clinicians should always be alert for RLS-like symptoms in one or both arms that worsen at rest and improve with movement, thinking of possible RAS. © BMJ Publishing Group Limited 2021.
