Well, yes, eye twitching can be a sign of epilepsy, so you should pay more attention to it. Generally speaking, eye twitching can come and go unpredictably for a few days, weeks or months. And also, it will not be painful, but annoying. But on the other hand, sometimes, it may be the earliest sign of a chronic movement disorder. For example, it can be the side effects of drugs, particularly medications used to treat epilepsy. By the way, for other causes, drinking, smoking, stress, lack of sleep, fatigue can be the common ones. So you need to be careful about it.
