BTW, they did blood cultures, and viral blood tests, all of which came back negative. Talk to me again after a doctor tells you you have a serious life-threatening condition right now. It gets your attention.
That's strange, pneumonia would be the main cause for lack of oxygen in your system.
I've had a life-threatening illness, meningitis, and my eight week old infant had it as well. Believe me, you're not the only one who has had this experience. Sheesh, I was only trying to be helpful!
Well, good luck with the mystery illness. Bird flu, maybe?
