====== Restless leg syndrome ====== //Restless leg syndrome,// also known as //Willis-Ekbom disease//, is a common condition of the nervous system that causes an overwhelming and irresistible urge to move the legs. Estimates are that around 10% of people suffer from RLS at some stage in their lives. It often occurs during sleeping hours and can cause severe insomnia.
