Cathy,
First thing that entered my mind was extra meds. They don't always translate and you should have a 'just in case' stash. I took Vicodin with me and it didn't touch my pain.
Also, funny but you kind of wear your own clothes over there, even in the hospital so make sure you have lots of comfortable things, for both warm and cold weather.
BTW, I'm so frustrated for you I could $&)(*$#!
