Also I still have bruises on my left arm. I hit it with my racket when I am doing forehands sometimes. For this reason I use two long wrist-bands to cover my arm below the elbow.
Then I realized, maybe Shiraishi has the same problem :)) (Of course not, he is a perfect player!). But I love his idea of wrapping his arm! I am planning to do that (ohhh, my otaku spirit!) :))
Though, I don't want to worry people, they might think that I have an accident :)
