Restless Leg Syndrome
Restless Leg Syndrome
Restless leg syndrome causes an uncontrollable urge to move your legs, usually at night.
Restless leg syndrome (RLS) is a neurological disorder in which one experiences throbbing, creeping, pulling, or other unpleasant sensations in their legs when sitting or lying down. The sensations create the irresistible urge to move the affected limbs which relieves the discomfort. Most people with RLS have difficulty falling and staying asleep.
Periodic Limb Movements are characterized by involuntary leg twitching or jerking during sleep. These sudden movements often make sleep difficult and result in poor sleep. The causes of each of these disorders are often related to other conditions or medications. A sleep study may help identify sleep-related causes, such as sleep apnea, which can make the symptoms more manageable.

FAQs
What's the difference between restless leg syndrome and periodic limb movements?
Restless leg syndrome (RLS) causes an urge to move the legs, often accompanied by uncomfortable sensations while a person is awake and resting. Periodic limb movements are involuntary movements or jerking of the legs that occur during sleep. The two conditions can occur together, but they are not the same.
Why do restless leg syndrome symptoms get worse at night?
RLS symptoms typically become more noticeable during periods of rest and are often worse in the evening or at night. This timing is one of the defining characteristics of the condition and can make it particularly disruptive at bedtime.
What causes restless leg syndrome?
There is not always one clear cause. RLS can be associated with family history, iron deficiency, pregnancy, certain medical conditions, and some medications. A healthcare provider can evaluate your symptoms and medical history to determine whether an underlying factor may be contributing.
How is restless leg syndrome diagnosed?
RLS is primarily diagnosed based on your symptoms and medical history rather than a sleep study. A sleep study may sometimes be used when another sleep disorder or nighttime movement disorder is suspected, but it is not routinely required to diagnose RLS.
Is restless leg syndrome treatable?
Yes. Treatment for RLS depends on the severity of symptoms and whether an underlying cause is identified. Treatment may include addressing iron deficiency, adjusting contributing medications, making lifestyle changes, or using medication when appropriate.
When should I talk to a provider about restless leg syndrome?
Consider talking with a healthcare provider if an urge to move your legs or uncomfortable sensations regularly interfere with relaxing, falling asleep, or staying asleep. Persistent RLS symptoms shouldn't simply be written off as normal restlessness.
