Left Pinky Toe Twitch

So for the past, oh, week or so I have noticed that my left pinky toe, and maybe my left ring toe, has been twitching.  I notice this when I'm at home.  Wonder if all my sitting down at work has anything to do with it.

I also wonder if it's Parkinson's.  If I recall correctly, Michael J. Fox noticed an uncontrollable twitch in one of his fingers while he and his wife were being driven by limo to some awards ceremony.  The finger was shaking so violently, and Fox was so spooked, that they had the limo driver drive around the block in the hopes that it would stop twitching.  Don't know if it did, but I think it was the first time Fox felt something was very, very wrong.  He got the diagnosis some time after.

Yeah, let's hope it's not Parkinson's.
