Bell’s Palsy

Bell’s palsy is a nerve disorder that usually happens suddenly and without warning. This condition happens when a nerve that controls facial movement is damaged. Nerve damage can happen for many reasons. But most cases of Bell’s palsy are probably caused by a virus.

Symptoms of Bell’s palsy

Here are signs of the disorder: 

  • Mild weakness to total paralysis of one side of your face

  • Drooping mouth, drooling on one side of mouth

  • Trouble closing one eye

  • Noises seeming louder than usual

  • Change in your sense of taste

When to go to the emergency department (ED)

There are conditions, such as stroke, that may look like Bell's palsy and are medical emergencies. Therefore, you should seek emergent medical care if you notice facial weakness or drooping. Although Bell’s palsy can be alarming, it’s rarely serious. Many people begin to improve in about 2 weeks, even without treatment. It is important to be seen as soon as possible. Most research shows that treatment with beneficial results was received within the first few days of symptoms. 


To treat Bell’s palsy, you may be given steroid medicines. This helps reduce swelling of the affected nerve. In some cases, your healthcare provider may prescribe an antiviral medicine. Your open eye may be covered with a patch to prevent it from drying out. You also may need to use eye drops and ointments for a time. Your healthcare provider will discuss follow-up care with you, including the possible need for further treatment to help your facial muscles return to normal.
