I feel like I'm telling people to google eyelid twitching. It's in a class of itself and it usually related to anxiety, tiredness or too much caffeine. With me, ALWAYS tiredness. Since I was a kid. It's so common among the regular population, trust me on this one.Even with my twitchy calf and foot, and eardrum, I usually laugh off the eyelid twitches I get from time to time. At least those are familiar and I know they are nothing dangerous and mean that I need more sleep.
