All About Restless Legs Syndrome (RLS)

Restless legs syndrome is a disorder of the nervous system in which people experience an irresistible urge to move their legs. In addition to the discomfort and distress that can accompany the condition, people with restless legs syndrome may find that they have difficulty sleeping. This post is all about restless legs syndrome and explains what causes it, what are the symptoms, and what treatment options are available for RLS.

What Are Restless Legs Syndrome?

People with restless leg syndrome experience unpleasant or uncomfortable sensations in their legs and have an irresistible urge to move them. The most common symptoms of hives usually occur in the late afternoon or evening hours and are often most severe at night when a person is lying down. Sitting for long periods of time can lead to leg cramps, which may occur when someone is inactive, and sitting for extended periods for example when taking a trip by plane. Your symptoms may increase in severity at night so it could be more difficult to fall asleep or get back to sleep after waking up.

Moving your legs or walking can temporarily alleviate the discomfort but the sensations are likely to come back if you stop moving. Restless leg syndrome is considered a sleep disorder because it’s often triggered by sleeping and also considered a movement disorder because it involves the restless leg muscle group, which has to be moved to relieve the uncomfortable sensations. It is best characterized as a neurological sensory disorder, and the symptoms are produced by the brain itself.

Symptoms of Restless Legs Syndrome

Symptoms of restless legs syndrome include:

Leg (or arm) discomfort: Adults often describe these unpleasant sensations in their limbs as creeping, itching, pulling, crawling, tugging, throbbing, burning, or gnawing. These feelings often occur at bedtime but may occur at other times of limb inactivity.

Urge to move legs (or arms): There are times when you want to move your limbs especially when you are resting, such as when sitting or lying down.

Sleep disruption: Most people need an extra half hour to fall asleep. When the urge to move your limbs to relieve the discomfort is strong. It’s not always easy to get quality sleep. Sometimes you may find it difficult to stay asleep.

Bedtime behavior problems: Because of the discomfort, you may have to get out of bed to stretch your limbs to relieve the discomfort.

Daytime sleepiness: Problems with falling asleep and staying asleep can cause daytime sleepiness.

Behavior and work performance problems: Due to poor sleep quality, many people experience daytime behavior problems (irritability, moodiness, difficulty concentrating, etc) and may have trouble focusing at work.

Diagnosis of Restless Legs Syndrome

You’ll need to have a complete medical history and a physical exam to help your doctor find out what’s causing your symptoms. In addition, tests, such as lab tests or a sleep study, may be done. Restless legs syndrome currently has no test to diagnose it.

The diagnosis of RLS in children can be especially difficult because the physician often relies on the patient’s description of symptoms. It is even more difficult when dealing with children to make a diagnosis of RLS when it comes to pediatric cases. Attention deficit hyperactivity disorder can sometimes be mistaken for growing pains or a case of not having an attention span.
