I had TN for almost three years. In the beginning I thought I was losing my mind and had all the symptoms discussed in this forum. About three months after its onset, a friend suggested I'd try acupuncture.
I did and it made a big difference. It didn't get rid of the TN but significantly lowered the pain level and also raised the level at which I would trigger an attack. I received acupuncture twice a week and the TN got better and better and close to disappeared. I'm 71 year old male and very fit, but my memory is getting worse. A friend recommended Ginko Biloba which supposedly increases blood flow to the brain and memory with it. Shortly after taking those pills, whatever the remnants of the TN were, the TN totally disappeared.
According to my doctor, any acupuncturist will know where to place the needles to treat TN. I wish more people knew about it, I didn't see any mention of it in TN forums. Good luck to all you sufferers!
