Do I have RLS? (Restless Leg Symptom)?

I always have the urge to move my arms or legs (especially legs, and when I'm lying down trying to sleep). It's really annoying when I'm trying to sleep. It's like a tingly/ticking feeling in my legs, it's hard to describe. It goes away after I move my legs/arms but them it comes back. The thing is, I'm 14 years old which is kind of young to get it apparently, BUT IT'S REALLY ANNOYING! I've done my research, do you think I have it? Thanks!
