Definition

Restless legs syndrome (RLS) is a nerve problem. It causes a person to move their legs without control.

Causes

The exact cause is not known. It may be a combination of genes, the environment, and other health problems.

Risk Factors

RLS is more common in women. It is also more common in people who are White and those who are over 65 years of age.

Other things that may raise the risk are:

• Taking certain medicines, such as antidepressants and antihistamines
• Family history
• Low iron levels
• Pregnancy
• Chronic kidney disease

Symptoms

Problems may be:

• An urge to move the legs
• Feelings of pins and needles, creeping, pulling, prickling, or pain in the legs
• Problems that get worse at night and make it hard to sleep

Diagnosis

You will be asked about your symptoms and health history. A physical exam will be done. This is enough to make the diagnosis. There is no test for RLS.

Tests to check for health problems that may trigger RLS are:

• Blood tests
• Monitoring of leg activity
• Sleep studies
