Hope you're fully OK, Martin.
When I came off a couple of weeks ago, I found that some of the pain didn't kick in until eight or nine hours after the event. My wrist, in particular, was no more than uncomfortable in the immediate aftermath of the crash in mid-afternoon, but it was bloody painful when I went to bed at around 11pm. It's still not right now, two and a half weeks later, so I sincerely hope you don't have any similar delayed-onset injuries.
