Welcome to RLS-UK. We are a registered charity, providing help and support to people living with Restless Legs Syndrome (RLS) and Periodic Limb Movement Disorder (PLMD). Restless Legs Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterised by an irresistible urge to move to stop uncomfortable or odd sensations. As it usually interferes with sleep, it is also considered a sleep disorder. RLS may start at any age, including childhood, and is a progressive disease for some, while the symptoms may remit in others. RLS-UK are here to lend an ear, offer advice and provide a community of people who understand what you are going through.
