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).
Also called (esp US): fall the season of the year between summer and winter, astronomically from the September equinox to the December solstice in the N hemisphere and from the March equinox to the June solstice in the S hemisphere. b. (as modifier): autumn leaves.
