Hello Lisa. I have MS as well.

I've had no personal experience with Tysabri, but we sure have plenty of members who do. I see that you've been given some good link so i hope you'll get some answers soon.

I'm so very pleased that you found your way to us, although I'm sad for the reason why. I hope to meet up with you in the MS Forums, and please don't hesitate to ask if you think any of us can help you out in any way.
