Eyebrow Twitching: Causes, Symptoms & When to See a Doctor

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.
