Bell's palsy is a weakness (paralysis) that affects the muscles of the face. It is due to a problem with the facial nerve. The weakness usually affects one side of the face. Rarely, both sides are affected. Many people who have a Bell's palsy at first think that they have had a stroke. This is not so.
