On certain occasions, individuals affected by restless leg syndrome may not be able to describe the sensations. They generally do not describe the feelings as numbness or cramping of the muscles. However, almost all of them have a perennial desire to hold or move the legs.
It is typical that the symptoms may alter in the severity levels over a period of time. Sometimes they may vanish for a particular period of time.
The usual patterns that accompany restless leg syndrome include the following:

The affected individuals typically engage in leg jiggling, stretching, exercising, walking or briskly pacing the floor to reduce the sensations. Restless leg syndrome gets its name from this forceful desire of the patients to walk or move, to get rid of the unwanted feelings.
