A functional neurologist believed that my TN was a result of a virus living in the nerve that goes dormant for periods. It seemed to flare up when I was having another illness I was fighting off, so it made sense to me. I followed precisely the regimen created by George. I did this beginning in January this year during a flare up. Several days in, the pain subsided. I have been pain free these past 8 months. This probably would not work if the cause is due to injury to the nerve. Hope this helps somebody else. So thankful to George for all his research and posting it. Here is his thread: Viral infection in the nervous system cause of Trigeminal Neuralgia and MS?
