Apparently my MRI looked great, but was reported as "inconclusive".
Doc said this means she can't say yes, but due to the symptoms, won't say no. She suggested it could be Lupus (I don't think I've been tested, but don't remember for sure). She gave me a referral to a new Neuro (mine is retiring), and that they'll order a LP for me to see more info.

The spot I thought I saw on the MRI was just brain, no lesions at all. I would have thought with migraines at least there would have been something. That's good!

I need to keep a notebook to track symptoms to show the new neuro. I should have done that a long time ago.
