The day of the Belmar Pro I was surfing down in Spring lake and my board hit me right in the face when I was under in the backwash. Right on the bone under my eye -- I took 29 stitches to sew it up. two hours later I was back in the water, I covered it with several layers of "liquid bandage." Sometimes called Newskin . . . it's basically a watered down cyanoacrilate, it hold things together and keeps water out. I was fine. The problem with your hand is that you keep flexing it, I guess. I had no problems surfing and the scar healed up great.
