I was diagnosed about 4 years ago with TN, but one thing that bothers me about the diagnosis is that my pain episodes often last for 20 minutes or more, sometime extrems for 20 minutes then reduced for a further hour or so. Whenever I read about TN the literature always mentions 'a few minutes' of pain. Does anyway with the same diagnosis have similar length episodes? I still can't be sure I have TN, or something similar. Thanks, look forward to hearing from you!
