multiple sclerosis
"I used to have about 3 MS flare ups and year, and had to be on steroids all the time, while taking other MS shots, that made me very sick. I have not had a single flare up, or taken any steroids or any other meds since starting Tysabri almost 5 years ago. Also no side effects at all. I even teach zumba classes now. Sometimes only hours after my infusion. It has truly changed my life."
