If it is just a occasional bout of small twitches that is not so worrisome, but if serious twitching of lid, face, mouth, you could have hemifacial spasm which could require a neurologic workup and possible treatment. So I guess it depends on the severity of the twitching. If is like you say, you should probably see a neurologist.
