What Is Bell's Palsy?
Bell’s palsy is a nerve problem that affects the muscles of your face. It causes weakness or partial paralysis of the muscles on one side of your face. With Bell’s palsy, your eyelid may not close properly and your smile may seem uneven.
Bell’s palsy usually affects adults only. It is more likely to happen to people who have diabetes, are pregnant, or have a family history of Bell’s palsy.
