Having Multiple Sclerosis you have to investigate your options when it comes to treatment, seven months after my initial diagnosis I started on Tysabri, one thing you have to get used to is monthly infusions. Now about 4 years ago I had gotten a tattoo on my right arm about seven inches from the palm of my hand. The 'tat' is of Cuba, for my past few infusions I have found it funny that my infusion nurse has had better luck finding a vein right off the coast of my tattoo. My left arm is bare in my "infusable" area. I know that it has more to do with the tattoo artist but I just think its kind of cool.
