Q. How soon do I need to be seen?

In facial palsy, an abnormal sensation is felt over a few hours to a few days with no clear cause, and the face becomes crooked as strength is lost around the mouth and eye.

When treatment begins affects the course. Generally the first 4 to 7 days after onset are taken as the important window. Missing it raises the chance of lasting after-effects, so if something seems wrong with your face, do not put it off; have it checked straight away.

Facial paralysis can also be a sign of a cerebrovascular condition. If strength is also lost in an arm or a leg, or speech becomes slurred, do not judge it as facial palsy yourself — go to an emergency department.
