My left eyelid keeps twitching. Why?

Its called a Tic. Usually it doesn’t mean anything bad.

**Just wanted to throw out one more possible cause, particularly relevant this time of year – allergies.

I have very severe pollen allergies which have become acute again over the past week. They occasionally cause eye twitches and other facial tics.

If your twitch just started last week, it might be worth checking to see if you’re allergic to something that bloomed recently. **

Wow! I’ve been thinking this for a few years now and I am so glad to hear confirmation (affirmation?). I finally put together that correlation and it seems to be true, though it’s slightly different every year (allergy season). Some years it’s extreme stuffy nose and other years it manifests as various twitches and other things. The physiology behind this must be fascinating.
