I'm new, but I've been suffering for 6 years. My mom was just diagnosed this summer with TN as well. She's typical, I'm atypical. Because of her I subscribed to TNA Quarterly. They have a questionnaire that helps to answer if you have TN and if you do what type. Go to google and type in trigeminal neuralgia questionnaire, it will come up at the top of the 1st google search page. ***** Hope this helps anyone with questions.
