Thanks for the responses everyone! I agree I should have used greater precaution, it just kills me to stay away from the water for so long.

The board hit me in the head as it was rebounding when I was surfacing. It wasn't too hard of a knock and the bump has subsided a little, it's mostly sore there and I still have a mild headache.

I also split my hand open and should probably allow that some more time to heal as well.
