Restless Legs Syndrome
About This Condition
Restless Legs Syndrome (RLS) is a poorly understood condition that causes leg symptoms shortly before going to sleep—symptoms that are temporarily relieved by movement. Occasionally the condition may also involve the arms. It can cause sudden jerking motions of the legs and can lead to insomnia.
RLS is most common in middle-aged women, pregnant women, and people with severe kidney disease, rheumatoid arthritis, and nerve diseases (neuropathy). Restless legs have also been reported to occur in people with varicose veins and to be relieved when the varicose veins are treated.1
Symptoms
RLS is characterized by an almost irresistible urge to move the affected limbs because of unpleasant sensations beneath the skin, which are described as creeping, crawling, itching, aching, tingling, drawing, searing, pulling, or painful. These symptoms occur primarily in the calf area but may be felt anywhere in the legs or arms. The sensations are typically worse during rest or decreased activity, such as lying down or sitting for prolonged periods.
Other Therapies
Symptoms may also respond to correction of an underlying medical condition, such as iron-deficiency anemia, kidney disease, diabetic neuropathy, amyloidosis, chronic venous insufficiency, or malignancy.
