Lower left lip twitching for weeks..numbness in the face mainly around my outer left eye.. after hours of twitching my face actually hurts..what is this?!

SeveralPossibilities: Most cases of a twitching lip may be due to stress, fatigue, emotion, excessive caffeine intake or some deficiency in the diet such as potassium. Lip twitching in most cases is self-limiting, disappearing in minutes or maybe in a few days without any residual problems. Persistent twitching, especially if associated with other symptoms, should be investigated. See http://bit.ly/1TPjy6c
