Why do my extremities randomly twitch?

Question

If I am sitting still for more than, say, thirty seconds, some part of my body will twitch. A foot will kick, a finger will twitch, a foot will flex... And it keeps happening unless I start moving around (it's actually happening now, since my hands are the only things that are really moving).

Why does this happen? My brother has said that it happens to him sometimes. I have ADHD, so is this in any way related (I doubt it, but you never know)?

Thanks!

2. the same things happen to me, only my finger twitches on and off though, sometimes so its probably either muscle spasms or nerve spasms.  its nothing serious though.
