I took my MRA/MRI films to my annual appointment. She did another vision field test, which I passed with flying colors again, despite my little blind-ish spot. Absolutely nothing is changed from a year ago, except that my pain is worse.
She gave me a little anatomy lesson sketch and explained why the suspected aneurysm on my internal carotid is unlikely to be the cause of my TN, as the 1st branch of the trigeminal nerve is pretty far away from that artery. She said she had been asking some others what they thought and someone suggested a nerve from the back of my head wrapping around to the eye, but she pressed all over and couldn't make the pain worse. The only thing that did make it worse was being dilated, and that was terrible for the rest of the evening.
She wants to be in the loop about what the neurosurgeon I see in two weeks has to say. I think she's as frustrated as I am. Especially with my insurance company that won't let me try Lyrica.
