Bell's palsy is a sudden onset of facial muscular weakening or paralysis. It starts quickly and intensifies over the next 48 hours. This disorder is caused by facial nerve injury (the 7th cranial nerve). Pain and discomfort are more commonly felt on one side of the face or head.

Bell's palsy is generally only transitory, with symptoms disappearing within a few weeks or months.
