KIDS DON'T HIT YOUR FINGERS WITH BIG HAMMER

I managed to hit my index finger extremely hard with a mash hammer prob about 3 months ago (an extra heavy hammer!), I jumped up and down swearing for a bit, it went blue and that was about it until now.
Now I seem to have 2 finger nails growing simultaneously, top ones about to come off I think, my real concern is that I have to play poker at Nigel's on Saturday with one hand.

...Have backblipped last 3 days from Belfast!
