I've always been curious as to exactly how hard it is to break one of those plastic board things that the TKD ppl seem so fond of so about two months ago I went to an ITF class and had a go. I broke it with each fist but my middle knuckles both swelled up and went purple, so I supose it was a draw bwteent me and the plastic.

Anyway, the right knuckle went down after a week and was quickly back to normal but the left one is still bothering me. It enlarged and although it doesn't hurt it goes purple again everytime I train. Note, I've stopped punching witb it altogether, it just goes purple when I'm warmed up. If I do punch, it bruises badly.

Has anybody got any experience of such testosterone related injuries? I've been using Arnica ointment with some success. What do you recommend for treatment. I've also been massageing it which seemed to help at first but now I'm not sure.
