Bell's palsy is paralysis or weakness of the muscles on one side of the face. Often people with Bell's palsy have a droop on one side of the mouth and have trouble completely shutting the eye on the same side. Bell's palsy can also interfere with the sense of taste. These things happen when a nerve in your face becomes inflamed. Bell's palsy is not caused by a stroke. The cause of the nerve inflammation is not known.
Bell's palsy usually gets better on its own in a few months. In some cases medicine is prescribed.
