Why is it twitching under my eye in the eye bag area? it has been more than 24 hours and its still twitching. i sleep good. i cant actually feel it but i can see it moving constantly. can i do something to stop it?

Muscle twitching is caused by minor muscle contractions in the area. Causes include lack of nutrients in the diet, medication side effects, lack of sleep, too much caffeine/exercise/stress, medical conditions that cause metabolic disorders, including low potassium, kidney disease, and uremia. Calcium /Magnesium supplement may help. If symptoms continue see a DR.

Sounds consistent with orbital myokymia, which is benign and self-limited, and unless spreads over the face, does not require medical attention. Should settle down over next several days.
