What causes a chin to twitch?

A twitching chin, or facial twitching in general, can be caused by various factors, including stress, fatigue, or anxiety. It may also result from muscle fatigue, caffeine consumption, or a neurological condition such as benign fasciculation syndrome. In some cases, it could indicate a deficiency in certain nutrients, like magnesium. If the twitching persists or is accompanied by other symptoms, it’s advisable to consult a healthcare professional.
