The Twitch

A month or so ago, I developed an eye twitch.  It isn't constant, but it happens every day at least once-always the same eye.  I doubt it means anything significant, but my eye is often "sore," as if there was somethinfn crusted in my eyelashes and I'd been trying to get it out.  I have frequent headaches, but that's nothing new.  

All causes I have found in my research suggest stress as a factor.  I don't feel particularly stressed, but I sure am annoyed by this darn twitch!
