I am on day 7 nonstop twitching under left eye in bag area. its a rhythmic twitch that never takes a break. i cant feel it but i can see it. ive tried everything but it keeps on twitching. should i be concerned?

You almost certainly possess orbital myokymia, which is a self limited transitory benign movement disorder, which should spontaneously stop. Can be caused by eyestrain, fatigue, lack of sleep, electrolyte imbalance. If this spreads to entire left face, this needs further investigation. If this is too troublesome see an opthalmologist for assistance.
