What is restless leg syndrome (RLS)?
Restless legs syndrome (RLS), also known as Willis-Ekbom disease (WED), is a common condition affecting the nervous system. It causes an overwhelming, irresistible urge to move the legs, and occasionally the arms.
Other symptoms include unpleasant feelings in the feet, calves and thighs, which are often felt as a crawling or creeping sensation. These sensations tend to begin or worsen during periods of rest or inactivity, such as lying or sitting.
What can cause restless leg syndrome (RLS)??
If there is no clearly identifiable cause, then the condition is known as primary restless leg syndrome – often attributed to lower levels of dopamine in the brain.
Secondary restless leg syndrome can develop as a complication of other health conditions, including diabetes, Parkinson’s disease or iron deficiency anaemia, among others.
