I was first diagnosed with a stroke... I had double vision for 16 months... two eye muscle surgeries to try and correct it... after the second surgery the double went away..I was on Aggrenox..blood thinner.. then I had another relapse in August of 2002..again with the vision.. so they did another MRI and all of the other standard tests for MS.. Well the stroke was gone, and strokes don't disappear.. plus I had three new lesions.. that's when they finally figured out I had MS.. I've been taking Rebif for the past five years.. I've been doing good since I started taking it...
