t may involve one particular muscle or group of muscles, or may randomly shift from one group to another. It also may include several different muscles or groups of muscles at one time.
The twitching may appear for a few brief moments, last for minutes or hours, or persist for days, weeks, or indefinitely. It’s also common for muscle twitching to persist or worsen when trying to rest or go to sleep. Muscle twitching also may stop when resting or sleeping then resume upon waking up.
Many notice that the twitching gets worse as stress elevates, but not necessarily lessens right away when stress is reduced.
All variations and combinations of the above are common.
The terms “nervous tick” and “nervous twitch” are often used to describe muscle twitching due to elevated stress and anxiety.
This symptom can affect ANY muscle or group of muscles in the body, including those in the head, face, eyes, mouth, neck, shoulders, back, chest, abdomen, groin, genitalia, arms, hands, fingers, legs, feet, toes, etc.
