Bell’s palsy is a sudden paralysis or weakness of the muscles on one side of your face that causes it to droop, and may make it hard to close your eye on that side of the face. You may also experience drooling, loss of the ability to taste, pain in or behind the ear, numbness on the affected side of the face, and a heightened sensitivity to sound.

Damage to the facial nerve that controls muscles on one side of the face causes that side of your face to droop and the nerve damage may also affect your sense of taste and how you make tears and saliva.

Bell’s Palsy is not the result of a stroke or a transient ischemic attack (TIA). While stroke and TIA can cause facial paralysis, there is no link to Bell’s Palsy, which may be caused by viruses, when the nerve gets damaged by inflammation.
