Restless Legs Syndrome

What is Restless Legs Syndrome?Restless legs syndrome, RLS is a sleep disorder that causes an irresistible urge to intensely shake the legs or even arms. It is also called Willis-Ekbom disease. It is accompanied by other sensations like pulling, tugging, itching, burning, throbbing, or creeping in the arms or limbs. These sensations happen when sitting for a long time or while sleeping. Since it happens mostly in the evening it results in difficulty falling asleep at night. RLS may be mild or severe and depends on the symptoms, frequency, and the disturbances it causes to the person suffering from it.
