Bell's Palsy Causes, Symptoms and Treatment

Bell's Palsy Causes, Symptoms and Treatment

Bell's palsy is a paralysis or weakness of the muscles on one side of your face. Damage to the facial nerve that controls muscles on one side of the face causes that side of your face to droop. The nerve damage may also affect your sense of taste and how you make tears and saliva. This condition comes on suddenly, often overnight, and usually gets better on its own within a few weeks.

The cause of Bell's palsy is not clear. Most cases are thought to be caused by the herpes virus that causes cold sores. In most cases of Bell's palsy, the nerve that controls muscles on one side of the face is damaged by inflammation.

Symptoms of Bell's palsy include sudden weakness or paralysis on one side of your face that causes it to droop. This is the main symptom. It may make it hard for you to close your eye on that side of your face and 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.

Most people who have Bell's palsy recover completely, without treatment, in 1 to 2 months.2 This is especially true for people who can still partly move their facial muscles. But a small number of people may have permanent muscle weakness or other problems on the affected side of the face.
