I came across this video of medical presentation regarding face pain and TN. The publish date is January 2013 and is about 55 minutes long.
The presentation by the surgeon covered many topics regarding TN. I found it very interesting and answered many of the questions I had; as I new to all this.
Thanks for posting this link. I just watched it and it was very helpful. I also liked that he repeated many times that the doctor must listen to the patient.
It really helped me understand the different medical procedures.
