Okay, I see. When hitting through boards (by hand) do you wear a kind of protective-tape or something?
Or do you simply get used to the pain?
Something like a towel or small layer of foam on the board to protect my knuckles from bleeding but other than that: if you hit hard enough and break the board it doesn't hurt. It starts to hurt when you don't break it because all the force applied into the board hits back into your arm usually damaging the knuckles. Had that once. Was painfull for about 2 weeks and sensitive for 4 more weeks. Nothing serious!
ETA:
very important thing if you're thinking about breaking something. Make sure it cannot bounce. If someone is holding the board and that person holds his elbows in an angle and not straight the board will bounce when you punch it and you won't break it and hurt your hand. So make sure the one holding it is holding it proper. If breaking something you can also use two solid tables or chairs whatever. Not light weigth stuff... They can knock over hitting you in the head. Put the board in between like a bridge. cover it with a towel and punch it properly with the right technique that was learned to you in a MA school.
