Well restless leg syndrome (http://www.ninds.nih.gov/disorders/restless_legs/detail_restless_legs.htm) can be caused by a variety of underlying medical concerns. And acupuncture is a traditional treatment used for many muscular problems so many believe it
can treat restless leg syndrome. However, there is very little evidence that acupuncture actually works, or, if it does work, that it works in the way that its practioners think it works. Studies have shown that the body will produce endorphins during acupuncture since endorphins are natural pain killers and you are being stabbed with something. This may help you with restless leg syndrome but you are better off looking for what caused the condition in the first place.
