Hi Kara, sorry for your troubles
I will have #54 Friday. Some nurses consider me a very hard stick others get me the first time. I have learned to drink fluids, keep my arms and hands (sorry they won't use your hands ) warm and tell them my veins are deep and rolling (I learned this a couple years ago from a nurse).

As for how long can we safely stay on Ty. I hope I will be on it until I no longer need to be on it.. a neuro at the RMmsC (Colorado) said that when you reach a certain age (65) for some ms stops or that something better has come along. I monitor my status-pretty vigilante... I pay attention to how I am keeping in mind signs of pml.

Tysabri has been/is a blessing for me !!!!!

Best wishes
Linda
