What are the symptoms?
The main symptom of Bell's palsy is a sudden weakness or paralysis in one side of your face that causes it to droop. This may make it hard for you to close your eye on that side of your face.
Other symptoms include:

  • Drooling.

  • Eye problems, such as excessive tearing or a dry eye.

  • Loss of ability to taste.

  • Pain in or behind your ear.

  • Numbness in the affected side of your face.

  • Increased sensitivity to sound.

How is Bell's palsy diagnosed?
Your doctor may diagnose Bell's palsy by asking you questions, such as about how your symptoms developed. He or she will also give you a physical and neurological exam to check facial nerve function and rule out more serious causes of facial paralysis.

How is it treated?
Most people who have Bell's palsy recover on their own within one to two months. But a small number of people may have permanent weakness of the muscles on the affected side of the face.
Your doctor may prescribe antiviral drugs, such as acyclovir, if he or she believes that Bell's palsy is caused by a virus. If your doctor suspects that Bell's palsy is caused by inflammation from another disease, you may be given corticosteroids, such as prednisone, to reduce the inflammation.
