What is known in medical circles as Willis-Ekbom disease, is commonly referred to as Restless Legs Syndrome, or RLS. This syndrome attachment tells you right up front that what we are dealing with is a condition that no one really understands.
RLS has a very broadly defined set of symptoms; it’s likely no two people will report the same exact complaints. The feelings that a sufferer of RLS may experience run the gamut: While some describe it as an intense pain, or ache, others can identify with “that itch that you just cannot scratch.” Some feel it as an unpleasant tickle, while others may perceive it as a crawling sensation.
The common theme is that people with RLS spend altogether much time trying to figure out what to do to get rid of it. Uncontrollable jumping, twitching or jerky legs often occur at the worst possible time when you are trying to sleep. RLS can lead to a number of consequences, none of them good, including depression, sadness, sleep deprivation, memory loss, stress and fatigue.
Since its causes are likely multiple and largely unknown, and there is no known cure, the current approach is to treat the symptoms.
