Bell's palsy is usually temporary, but sometimes its effects on the body are long-lasting or even permanent. People with Bell's palsy have weakness or paralysis on one side of their face. They may find that their sense of taste is dulled and that sounds are very loud in the ear on the affected portion of their face. It is hard for many people with Bell's palsy to blink or close their eye on one side. Eye dryness can be painful and can lead to eye damage if not treated. Some people experience facial twitching or problems with drooping or contracted muscles even after their other symptoms have disappeared.
