Perhaps these notes I've written can be of use to someone else, who might take precautions prior to the onset of facial paralysis. I've personally found the whole thing very taxing emotionally. Indeed, Bell's palsy, or facial palsy as it is also known, is a temporary inflammation of the facial nerves on one side of the face. It is a pretty common condition that usually affects people suddenly. Treatments may include anti-inflammatory drugs, analgesics, pain killers, facial muscle exercises, and taping shut the eyelid during bedtime.
Facial palsy clears up in most cases, with or without treatment.
