I'm so very sorry that you are dealing with this for so long. Keep in mind that nerve tissue is very slow to heal and there is still hope that improvement can happen. Perhaps research into Lion's Mane mushrooms. I felt that I regained more facial nerve control when I started on them and it was already years after the initial surgery. They can delay blood clotting so if you are on a blood thinner I would avoid using it, or have any dental or surgical procedure you have to be aware to stop using it. Good luck and stay positive.
