I cut a big nerve in my thumb years ago, and apparently plastic surgeons fix that sort of thing.
They reattached the nerve bundles, but I was told the sheathes could be realigned, but the nerves would have to grow back from the point of the cut all the way to the skin.
At first one half of my thumb was entirely numb, and over the course of well over a decade I'd get pins & needles as bunches of nerves would finish regrowing, except attached to random channels in the nerve bundle, so my brain had to completely remap all those signals to what they actually meant. Also extreme nerve pain near the cut whenever it was bumped, I assume because many nerves just didn't grow successfully and remained near that site.
It felt super weird because hot, cold, pain & touch were all mixed up, but eventually my brain sorted them out. It still feels a little weird, especially near my nail, but I haven't had a pins & needles experience for a few years.
The problem with doing that with a neck is that it would take wayyy longer and the chances of the patient dying from complications due to no brain signals working right... yeah I don't see medical science fixing this unless we can regrow nerves in a much shorter span of time.
See, I just don't connect it to the network. It complained when I set it up but now it just works as a screen.
I've got a raspberry pi steaming my desktop to it with gamestream/sunshine/moonlight, and it's now as smart as my computer. It can even stream from different computers no matter where they are in the house, watch anything with stremio, and play games from them too. It's way better than using the youtube or netflix button on the TV, most of the services it offers I don't use anyway.
But actually pihole does sound like a good idea and maybe I should get that set up one of these days.
