What is Restless Legs Syndrome (RLS)?
Restless Legs Syndrome is a crawling, tingling or painful sensation in the legs that occurs while lying or sitting for an extended period of time. People with the disorder describe an irresistible urge to move their legs when the symptoms occur. The limbs may also move or jerk during sleep. It may affect one or both legs and arms. It affects both men and women, and it is more common among older people.
What are possible causes?
-
Heredity - be sure to tell your physician if you have a family history
-
Chronic diseases - Diabetes, arthritis, peripheral neuropathy and kidney failure may all be associated with RLS
-
Low levels of iron or anemia
-
Consuming too much caffeine
How is it diagnosed?
Unfortunately, there is no test that can accurately diagnose RLS. Diagnosis is usually based on the symptoms you describe to your physician. Basic lab tests may be done to rule out other causes, such as low levels of iron and anemia. Your physician may even recommend a sleep study, or polysomnography (PSG), during which the patient is observed overnight in a sleep lab.How is it treated?
Simple things like massaging the legs, exercising and reducing caffeine consumption may provide some relief. Medications can also be prescribed to control symptoms, and in more severe cases, electrical stimulation may be used before bedtime on the legs to help reduce leg movement
