Uncomfortable sensation in the legs with a clear need or urge to move the legs. The sensation may be described in many different ways from aching and pulling to creepy crawling feelings. The sensations can also be painful, not just uncomfortable. But in the end, all sufferers can clearly identify a need or urge to move the legs as a driving force behind their complaint. Some individuals may have symptoms not only in the legs but also in the arms or body.

The symptoms are worse at night. This may be only at bedtime or it may start in the evening when trying to sit for any period of time. Some individuals may have symptoms throughout the day but these symptoms can often be worse at night.

The symptoms come on with rest. Whether trying to lie quiet at bedtime or sitting through a long plane flight. The sensations are likely to occur. Whether trying to sit through a movie or quietly reading a book, the symptoms will make what used to be an enjoyable event, a most unbearable one. You cannot rest; you cannot relax; you cannot sleep another night.

The symptoms are relieved with movement. All sufferers learn quickly that getting up and walking will immediately relieve the symptoms. However, as soon as the individual settles back into a restful state the symptoms will usually return. Any movement of the legs will usually bring about some immediate, although temporary relief. If the legs are not moved, they may jump on their own. In some individuals, there may be semi-involuntary movements of the legs preceded by only a very brief sensation. Most individuals with Restless Legs Syndrome will have rhythmic or semi-rhythmic movements of their legs while they are asleep. Although they may not be aware of their movement, usually their bed partner is. It is this movement of the legs, this constant walking to ward off the sensation, that gives the viewer the perception of the sufferer being restless, thus the term Restless Legs Syndrome.
