I had a car accident in July 1999, around September '99, I started developing these red lumpy blotches all over my body, turned out to be psoriasis. Had my first bout with ON March 2000. The psoriasis seems to be the clue that my autoimmune system was out of sync. It's a long, story why it took so long for me to return to any neurologist between 2000 and 2007. Lack of health insurance, and feeling that since my bouts with ON cleared up, really, what was there to do?

But, it's possible that symptoms can exist longer that are unexplained and unaddressed before going through the testing to get to the dx.
