Restless Legs Syndrome

“Restless Legs Syndrome (RLS) is a disorder of the part of the nervous system that causes an urge to move the legs. Because it usually interferes with sleep, it also is considered a sleep disorder.

People with restless legs syndrome have uncomfortable sensations in their legs (and sometimes arms or other parts of the body) and an irresistible urge to move their legs to relieve the sensations. The condition causes an uncomfortable, "itchy," "pins and needles," or "creepy crawly" feeling in the legs. The sensations are usually worse at rest, especially when lying or sitting. The symptoms are generally worse in the evening and at night.

Causes:

·doctors do not know the cause of restless legs syndrome but suspect that genes play a role.

·Certain chronic diseases and medical conditions, including iron deficiency, Parkinson’s disease, kidney failure, diabetes, and peripheral neuropathy often include symptoms of RLS. Treating these conditions often gives some relief from RLS symptoms.

·Some types of medications, including antinausea drugs, antipsychotic drugs, some antidepressants, and cold and allergy medications containing sedating antihistamines, may worsen symptoms.

·Some women experience RLS during pregnancy, especially in the last trimester. Symptoms usually go away within a month after delivery.

·Other factors, including alcohol use and sleep deprivation, may trigger symptoms or make them worse.”
