Sadie for 6 years I got told by dentists ( 4 different ones) that I did not have trigeminal neuralgia whilst they laughed at me for even suggesting it.
I was too young "apparently".I work in a hospital and a medical records staff member "diagnosed" me as he was walking past my desk at the very start of my days of pain.It really hurt that they laughed at me and I sometimes think that I would like to write to them, but hey they are dentists and so far up themselves they wouldn't care.
I should have gone to a Neurologist years earlier. I now have one and he is great. Pain free for now ( on medication) and loving it
