Restless legs syndrome (RLS) is a neurological disorder characterized by uncomfortable leg sensations that can interfere with resting or falling asleep. Experts believe that low levels of iron in the brain may be responsible for RLS. An imbalance of dopamine is also believed to be involved. About 60% of people with restless legs have a family member with the condition, indicating a strong genetic component.

Anyone can have restless legs syndrome, but it's more common in older adults and women. Mild symptoms of RLS may start in early adulthood and then increase with age. After age 50, RLS symptoms often increase in severity and significantly disrupt sleep. Restless legs syndrome is also common during pregnancy (approximately 40% of pregnant women experience it).

Some have said it feels as if bugs are crawling up their legs, a fizzy soda is bubbling through their veins, or they have a "deep bone itch." Sometimes the symptoms are painful, but most often they are simply uncomfortable and disturbing.
