Bell’s palsy is a condition that causes a temporary weakness or paralysis of the muscles in the face. It can occur when the nerve that controls your facial muscles becomes inflamed, swollen, or compressed.
The condition causes one side of your face to droop or become stiff. You may have difficulty smiling or closing your eye on the affected side. In most cases, Bell’s palsy is temporary and symptoms usually go away after a few weeks.
Although Bell’s palsy can occur at any age, the condition is more common among people between ages 16 and 60. Bell’s palsy is named after the Scottish anatomist Charles Bell, who was the first to describe the condition.
