THANKS TO MIMI, ONE OF OUR MODERATORS, FOR POSTING THIS IN A DISCUSSION. I AM JUST POSTING HERE TO SHARE WITH ALL WHO DID NOT SEE THAT DISCUSSION.
This is EASY to watch/read, and is short and informative. I hope our moderators will choose to add it to the "Face Pain Info" section. It's a basic description of the disease and treatments, there's not much about atypical TN or all the various treatments, but great animations and understanding just the same. University of Manitoba is a leading edge research hospital for TN in Canada.
