What is it?

Bell's Palsy (also called facialis, facial paralysis) is a condition that causes weakness or paralysis of one half of the face. The paralysis is caused by damage to the nerve that innervates the face. The exact cause of this damage is unknown, but it may be triggered by a viral infection. Bell’s Palsy shares several characteristics with stroke, so it is important to undergo a medical examination that is able to differentiate between the two.
Most people with Bell's palsy recover completely, but Some people are left with lifelong damage.
