Overview & Considerations
Muscle twitching is the result of minor local muscle contractions or the uncontrollable twitching of a single muscle group served by a single motor nerve fiber or filament.
Muscle twitches are minor and often go unnoticed. Some are common and normal, while others indicate a neurologic disorder.
