Kat, isn't that sad? Poor kids who have to deal with that. I've heard even babies can get it.
The worse case I've heard of, was a man who had severe RLS symptoms, but his legs had been amputated many years prior. The poor guy couldn't get up and walk, or massage, or do anything to his legs to try to make the pain/sensations stop. Turns out, he responded to meds eventually, but it shows that it's not happening at the level of the legs at all. But what a nightmare situation. It's hard to complain when you hear of stories like that.
