Bell's palsy is a condition that causes temporary weakness or paralysis of the muscles in one side of the face. It is the most common cause of facial paralysis
The symptoms of Bell's palsy can vary, from a mild numbness of the face, to total paralysis. It can also affect the eyelid and mouth, making it difficult to close and open them.
Bells palsy occurs when the nerve that controls the facial muscles (facial nerve) becomes inflamed or compressed. It's not known what causes the facial nerve to become inflamed, although it's thought that a virus, possibly a herpes virus, may be responsible.
There is no specific test to diagnose Bells palsy. However, tests can be used to rule out other conditions that cause facial paralysis. It's important to see a doctor to determine the cause.
Prednisolone is recommended as the most effective treatment for Bells palsy, and it should be started within 72 hours of the symptoms appearing. Most people recover fully from Bell's palsy within nine months.
