multiple sclerosis
"In July of 2014, I was given the diagnosis of MS.  The medicine has worked well for me so far.  I have headaches after infusions, they don't last long. I take Cambia for the headaches. Tysabri helps me to walk, drive, travel, and keep my job. My dizzy spells don't happen as much.   Tysabri is the only medicine I've taken for MS.  I am still in shock from being diagnosed with this condition. I am very happy Tysabri,even with the risks of JCV and PML."
