Hello, I just started reading your posts. I need to ask a favor. In short, My tn started March 2009. I had gamma knife in june which was very successful. In July I was in an auto accident and the tn came back much worse than before. Then in the fall I started getting this burning, stabbing, numb, pulling, heavy, electric shocks to my face. What I have read, this is ad. I can't find any literature that an auto accident can cause this. I will be going to trial for the accident and I was wondering if you have any information that would be helpful for me. Thank you so much.
