I started twitching in my eye around December 02 within a month I was twitching all over. Some people twitch when they are stressed.
If you look on the board here called "rare disorder" you will find posting on benign fasciculation syndrome. It's twitching with no real cause. Nothing sinister, just annoying.
I hope yours doesn't progress to other parts of your body. I'm not trying to scare you. I just want to keep you aware that it could stop, but if it doesn't, there are other twitchers to help you.
Mine was so bad I had to see a neurologist. I was worrying so much.
I know it's hard to ignore the twitching in the face. It's so obvious.
