No, I've never had an LP. What is that used to diagnose?
I'm sorry to hear that your breathing got so bad you had to have a hospital stay. That's the one thing that really concerns me (and I think that's what convinced the neuro to re-run the tests)... I've had breathing issues and I'm so afraid of being home alone with my young kids and having my breathing get really bad or stop! It only got bad enough once for me to go to the ER, but by the time I actually decided to go and then waited to be seen, my breathing regulated again. Scary stuff!
