2. What is Bell’s palsy?

Bell’s palsy is damage or disruption of the facial nerve controlling the muscles of the face. This interrupts all the signals the brain is sending to control the face, leading to facial weakness or paralysis. Usually, the condition only affects one side of the face. Symptoms vary from person to person, but drooping of the eyelids and corner of the mouth are typical. The symptoms reach their peak after 48 hours. Women and men are equally likely to be affected, but it appears more commonly between the ages of 15 and 60.
