Mine has twitched for a coupla days. That normally means ur stressed or ur missing something from ur diet...like potassium or something like that. I cant remem what it was exactly though. It went away after a coupla days.
Yes it's a it's a nerve but the only way to stop it and I talk to my doctor about it was to get BOTOX and I didn't want to do that because that's some type of drug going into your body that's not healthy
