Is it normal for one of your eyebrows to twitch all day?

No, it is not normal for one of your eyebrows to twitch all day.

Eyebrow twitching, also known as a brow twitch or an eyebrow spasm, is a common condition that usually affects only one eyebrow at a time and typically resolves on its own within a few days or weeks. However, prolonged or recurrent eyebrow twitching could be a sign of an underlying neurological condition and should be evaluated by a healthcare professional.
