Bells Palsy is an idiopathic condition. It has no certain cause, but the HSV1 (cold sore virus) is thought to be the culprit in most cases. You do not have to have had a cold sore to have the virus in your body. There are many possible causes for Facial Palsy, so Bells Palsy should not be diagnosed until all other possible reasons for the paralysis have been investigated.
