====== COVID-19 Vaccine Associated Facial Nerve and Bell's Palsy ======

Facial paralysis and Bell’s palsy are distinct diagnoses, but both involve paralysis of the facial nerve.  A cause for the paralysis can be identified for a diagnosis of facial paralysis, where as in cases of Bell's Palsy the condition occurs without an apparent cause. lies in how the conditions are diagnosed. 

Facial paralysis, for example, can be linked to a tumor, infection, or nerve damage. 
 
The symptoms of facial paralysis may persist and may never disappear, they can escalate over time.  Surgical treatment may be necessary and effective.

Bell's palsy is also known as "acute peripheral facial palsy of unknown cause."((https://www.mayoclinic.org/diseases-conditions/bells-palsy/symptoms-causes/syc-20370028))  It is believed to be caused by inflammation of the nerve serving the muscles on the side of the face. It can be caused by a viral infection or may arise following vaccination.
