Hello Michelle, welcome to NeuroTalk.

I'm so sorry for your DX of MS, but glad you found us. I have had MS
for 48 years, DXed for 37 years. So, it is not a death sentence or the
end of your life, as you know it. I'm still here and going strong,
most of the time.
Tysabri is a favorite of a lot of Neuros, because it is effective in many
cases, but not all cases and it does have a danger of contracting PML
(an evil and sometimes deadly disease). Your Neuro should have you
tested to make sure you are not a possible candidate for PML.
No Med we have out there for MS, is a cure, and some have debilitating
side effects, so the decision to take one is yours. Educate yourself about
all of these meds and then, if you wish, you and your Neuro choose the
one that is best for you.
Thanks for joining us and I wish you the best.
