Thank you glenntaj for the excellent info. It makes a lot of sense. And I also like the idea of Guillain Barre syndrome because it means that the worst should be aver and I should start feeling better!

I did have a brain MRI 2 weeks ago. All my doc said about it was, 'fine, no MS, may indicate migraines.'

I looked up the actual test result today and what it said was 'multiple small hyperintensities' which are commonly associated with things like migraine. Which means tissue damage - in my brain.

I should not have read those test results. It's very upsetting to read that your brain is damaged. And I have trouble managing anxiety since this all started, and I feel twice as bad when the anxiety really gets going.

I never had headaches before this. Shouldn't it take more than 2 months of migraine symptoms to damage my brain enough that is visible in an MRI? Maybe like glenntaj said- the initial infection did that damage.
