Well Crap...Thank you Marie for the input. I was afraid of something like that happening. My fingers are crossed that I get my infusion on time. I do feel the tysabri wearing off about a week before, I guess thats why I'm nervous. About a week before I can't wait to go to the Procedure center to get my infusion, and I HATE needles so it doesn't make sense, until the next day when i feel so much better. Well whatever happens, happens, as my Physical Therapist told me "You wouldn't have been given this disease if you wern't strong enough to handle it"
