"nerves with the covering worn off by the pulsing blood vessels near the base of the brain" is how Trigeminal Neuralgia is related to MS. I have been seeing this written up a lot lately. I am going to get an MRI and other neurological tests, next week. Hows that for FAST in Canada? I only had the attack and my ER visit a week ago. But it isn't exactly Trigeminal Neuralgia, but it is "face pains on the Trigeminal nerve". My attacks do not come on suddenly, and they last much longer than typical TN [about 2 to 3 hours]. Other than that, it is just like TN, I think. Anyone else here have Trigeminal Neuralgia attacks that last longer than a few minutes?
