Restless legs syndrome (RLS) is characterized by unpleasant sensations in the limbs, usually the legs, that occur at rest or before sleep and are relieved by activity such as walking. These sensations are felt deep within the legs and are described as creeping, crawling, aching, or fidgety.
In North America, autumn is usually considered to start with the September equinox (21 to 24 September) and end with the winter solstice (21 or 22 December).
The meteorological seasons in the Southern Hemisphere are also opposite to those in the Northern Hemisphere: Fall (autumn) - starts March 1 and ends May 31; Winter - starts June 1 and ends August 31; Spring - starts September 1 and ends November 30; and, Summer - starts December 1 and ends February 28 (February 29 in a Leap Year).
