Here's a thread for everyone to list their diagnoses.
I was diagnosed with persistent migraine aura without infarction for my visual symptoms. The diagnosis was from a neuro-ophthalmologist who said he'd seen a few dozen patients with the same symptoms. He also said none of them has ever seen improvement, which was not particularly encouraging.
I also have complex migraines, a few kinds of seizures, an autonomic nervous disorder, and multiple sclerosis. Basically, my brain seems to be out to get me.
