My almost 10 year old has had episodes of muscular tics or something. This just started the day before yesterday. It doesn't appear totally involuntary, but more like wiggles she just HAS to get out. I tried google but it wasn't all that helpful. any ideas? She'll jump up and shake a leg out, or just start shaking her hands. This continued in school yesterday. She is a bit embarrassed and seems like she is trying to control it or at least wait until (she thinks) no one is looking.
