A nerve disorder that occurs when a nerve that controls facial movement is damaged. Bell's Palsy is usually sudden and in most cases caused by a virus. Symptoms include mild weakness to total paralysis of one side of your face, drooping mouth or drooling on one side of the mouth, trouble closing one eye, noises sounding louder than usual and a change in your sense of taste.
Bell's palsy rarely requires emergency treatment but you should seek medical care right away. Steroid medications will help reduce swelling to the affected nerve and your doctor may prescribe an anti-viral medication or other treatments to help you recover.
