B-12 was one of the first things they checked when I started having facial pain. I was in the low normal range and my neuro told me to take 1000 mcgs per day. It's supposed to help keep your nerves healthy. I'm now taking 500 mcgs every other day and my levels are in the high normal range.

I hope your numbness goes away. That would be a very weird feeling. Did you have any twitching with your TN? I have twitching in my cheek, lip, nose and under my eye. It's usually not visible, but I can feel it. If I mention it, the doctor just says something about it being a different nerve and won't give me any explanation.

I hope your recovery is going well.
