CV and mad panic behaviour

[Mav]

When I had it, the first symptom was it changed my perceptions of taste: I was at a restaurant and I was p!55ed off that the meal I'd ordered had an overpowering taste of orange. The woman I was with tasted it and said there was no orange taste at all. Then later that night I woke up with the pillow case touching my eyeball. From there, my inability to close my eye was very obvious and I needed an eye patch and one side of my face including the corner of my mouth just dropped. The way the doctor explained it then was a facial nerve had died but it would regrow in time. I was warned, though, that sometimes the regrown nerves didn't connect correctly with the existing ones, like rewiring the electrics in a car and getting left and right indicators mixed up. An example, apparently, was the TV journalist Paul Lyneham who had a weird grimace when he tried to smile. Fortunately for me it all went back to normal.

While causation still seems to be a mystery, viruses seem to be a suspect. In my case, I hadn't had any flu or other virus AFAIK. Is there some virus which is asymptomatic other than initiating Bell's Palsy? Could those who have recently contracted Bell's Palsy have suffered breakthrough Covid infections that were asymptomatic other than initiating Bell's Palsy? As the mRNA vaccines don't contain live virus, would they even have the ability to kill facial nerves? What are the chances that an immune response generated by this vaccine would be so specific as to kill facial nerves and nothing else? It's all very speculative but very interesting all the same.
