It started yesterday, and I thought nothing of it. But since it's still happening today, I think it might be bad. It has little twitches every few seconds and it's getting on my nerves. (Which could possibly be part of the problem.) Keeping a finger on my eyebrow stops the twitching for as long as it's there, but a permanent solution to this would be preferable, as the constant twitching is giving me a headache.
