I had a problem with an eye twitch many years ago. When I was in nursing school, I had a teacher for one semester, that took a dislike to me. The eye twitch started at the beginning of the semester with her, and ended immediately when the class was over. Pretty obviously stress induced in my case.
Can you pinpoint a stressful situation(s) that occurred just before the twitching began?
I agree that these symptoms are caused by anxiety/stress. Anything that you can do to relax yourself should help, and once the stressful situation has resolved itself, that should help too.
As always, the very best to you!... Chuck
