Restless Legs Syndrome: A Common, Underdiagnosed Disorder

Restless legs syndrome (RLS) is a common sensorimotor disorder of the central nervous system. It is characterized by an irresistible urge or need to move the limbs that occurs as a result of uncomfortable limb sensations. Although RLS usually starts in the legs, it can spread to other parts of the body, such as the arms or torso. RLS sufferers often describe the disorder as feeling like water flowing inside the legs, “bugs in the bones,” or electricity in the legs.
