Hey, Brandi! Since you have known neck problems, this might indicate a pinched nerve. I'd recommend seeing a chiropractor or a neurologist. Nerve issues aren't anything to fool around with, especially since you have a physically demanding career (sand sculptures, right?).

Then again, if it's an isolated situation, maybe you just had a crazy dream and were clenching your fist or something!!!

If this isn't an isolated situation, I wouldn't ignore it.
