I just wanted to post a link to an article written by a NUCCA Dr. on Facebook that I have had the pleasure of speaking with. For anyone with ATN and symptoms that span mixed nerves or symptoms that are all over your head, face, neck and beyond I urge you to at least read up on this belief. I know it is not for everyone and I know that many of us have tried chiropractors without luck but I really think there is something to this.
I've been wading through the very long article in the link you provided, Jane. So far I've seen a large volume of text and pictorial material that has nothing to do with trigeminal neuralgia. I've also seen some claims that are just outright factually wrong, even if chiropractors believe them vociferously. Contrary to the claims of this article, the bones of the cranium do NOT "move" and cannot be manipulated by chiropractic means. For a contrary view, see "Cranial Manipulation and Tooth Fairy Science", on a site called "Science Based Medicine" at https://www.sciencebasedmedicine.org/cranial-manipulation-and-tooth-fairy-science/ . You may find the extensive comments to the article useful as well.
