The nerve exactly under my right eye is tapping like a pulse from the past 5 days. it starts after every 2 minutes. i'm getting enough sleep. help?

Not to worry: It sounnds like you have a condition called myokymia, which is very common. We don't know what causes it and it is probably not related to sleep, stress etc. It is a benign condition and the vast majority of the time, will resolve on its own within a few days. On the rare occasions that it does not go away within a reasonable period of time, a single injection of Botox can do wonders.
