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).
There are 4 astronomical seasons in a year: 1  spring-March Equinox to June Solstice, 2  summer-June Solstice to September Equinox, 3  fall (autumn) - September Equinox to December Solstice, and. 4  winter-December Solstice to March Equinox.
