I was newly diagnosed with MS 3/12/14. I had my initial symptoms in December of 2013. I was found to have multiple lesions on my brain and spinal cord, and the doctors were kind of surprised I hadn't had symptoms sooner. They now want to start me on Tysabri, since I am so young, and I do have all of my function as of now. I am deathly afraid of Tysabri, and contracting PML. I am looking for some guidance with this. I have been researching the drug, but it says you can get PML even after you have stopped taking the drug. I know this drug is supposed to really slow things, and I do want to preserve as much functionality as possible, but I want to BE ALIVE.
