multiple sclerosis
"I was diagnosed with multiple sclerosis in 2007, 5 days after my 23rd birthday. For the first year I took Copaxone, and it did absolutely nothing for me. Then, since my MS was so aggressive, my doctors chose Tysabri for me. I have loved every minute of being on the medication. Not only have I been stable for 4 years, but my old lesions have shrunk in size. Unfortunately, due to being on the mediation for so long and coming back with a positive JC Virus test I am being taken off the medication which scares me to death. My advice to anyone considering the wonderful medication is that you have a serious conversation about the possibility of PML while on the medication. It's a choice of life or death. 1 in 250 people on Tysabri with a positive test are at risk."
