Hi!
I am happy to see I am not the only one. I have pins and needles 24/7 on my tongue and the roof of my mouth - since my accident (TBI) four years ago! I was told it has to do with damage to the cranial nerves in my case. Perhaps that is the same for you? They are all different and go in different parts of the body and face and neck.
I am trying to get used to it, like the tinnitis 24 7. But some days I am fed up with it!
hope you are improving!
