Bell’s Palsy
Bell’s palsy is a weakness or paralysis 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.
In most cases of Bell’s palsy, the nerve that controls muscles on one side of the face is damaged by inflammation.
Many health problems can cause weakness or paralysis of the face. If a specific reason cannot be found for the weakness, the condition is called Bell’s palsy.
