As I stated in my application, I am here because my sister suffers from TN. Hers is caused from her Multiple Sclerosis. I was wondering if anybody here has TN related to MS. She is considering having the CyberKnife treatment. Has anybody here used this method of treatment? I only know second hand how horrible this pain is for all of you. I will keep all of you in my prayers as I know the God can provide strength for you. Hugs, Lonna
