Irritable leg syndrome, also called restless leg syndrome (RLS), is characterized by any number of unpleasant sensations in the legs. People diagnosed with this disorder describe feeling a dull aching, restlessness, burning or tingling in the legs. Symptoms typically appear at night when the individual is inactive, and mostly dissipate in the morning.
Facts
The Restless Leg Syndrome Foundation reports that 10 percent of the U.S. population suffers from this disorder. It can diminish quality of life by causing sleep deprivation and insomnia. Stress can exacerbate RLS symptoms.
Causes
Researchers at the Heart Blood and Lung Institute believe that irritable leg syndrome is the result of a dopamine imbalance in the brain. Dopamine is the chemical that controls muscle movement. Nerve damage and the use of some medications have also been linked to RLS.
Who Gets Irritable Leg Syndrome
This syndrome can affect any race or ethnic group. Women are more likely to have irritable leg syndrome than men. It's also commonly diagnosed in the last three months of pregnancy. Some people who develop RLS show symptoms before the age of 20.
Symptoms
A diagnosis for RLS is typically based on four characteristics:
An unpleasant feeling or pain in the legs, accompanied by an urge to move them continuously.
When discomfort in the legs is worse at night and lets up in the morning.
When symptoms are experienced while the individual is lying down, sitting still or at rest.
Walking or other leg movements relieve leg discomfort.
Treatment
Irritable leg syndrome has no cure. At this time, doctors aim to reduce discomfort and minimize symptoms and occurrence. Individuals with RLS have reported improvement when they increase physical exertion prior to bedtime or implement a strenuous exercise routine during the day. Stretching and massage may help as well.
