ok, my only experiece was to break my foot's little finger (I was 27...) and I'm sure it lasted for more than 5 days, although it wasn't very intense. I'd ring them and explain the situation. at least to have an idea of how long is expected the pain to last. probably it's not very common to put a cast for a little finger, but it's worth to try. (and this would need a very apprehensive italian mother emoticon).
don't worry, I knew about your dodgy connection . yes, it'd be lovely to meet up again!
