MrsD, thanks for taking the time to share this info. Lots to think about. I have tried hard to think of possible triggers that could have led up to my sudden onset. Two of the weeks I spent in the hospital were with an infectious disease doc who was looking for anything and everything infectious that could have caused my brain lesion or other symptoms. She ran so many tests that on one of those days she drew 29 vials of blood. And that was just one day!

I haven't been out of the country in over a year, but I think you are right that it is possible i picked up something that has been dormant for awhile. Hmmm. I was in some pretty remote countries.

Thinking about things that preceded the onset: i took a trip to california, but only saw the beach and Disneyland. Other than that trip, I had been so busy at work that I hadn't been far outside of my office building or my apartment complex for months. I live in phx and i have no farms or strange animals around. I don't even have pets.

I just don't know. Thanks for chiming in on the mystery. I really appreciate having people to brainstorm with.

Mandy
