You will be fine LR:

I have been to Mass General. I went there after THREE other stinkin hospitals couldn't get it right....with my
"Abdominal Aortic Aneurysm". Mass General got it right the first time they tried..(10 Hours).... and by the time I got there.... they only had hamburger to work with.. That was 14 years ago. No problems since.
Mass General is the
THE BEST IN THE WORLD. This is not just MY opinion..it is the opinion of their peers....and has been for awhile.
