I've got this as well, and i can't play properly because of it. Being as i was predominantly a singles player, with a game based around netshot, smash and accurate clears, who used head-heavy rackets with a long grip (voltric z-force 2). I've tried to play twice in the last 2 years. Couldn't hit a clear or smash that didn't hurt and worse, it doesn't feel right anymore, like my swing is compromised. Which I guess it is. I've slowly gone through my action and my arm won't go back far as i'd like or impart that elastic snap. (affects timing?) Also its trying to drag away from my body which compromises both power and accuracy. I miss playing, and I suspect its never going to be possible to play like before. I'm actually wondering if i can completely rework my technique and play style to compensate. ie if I improve my wrist strength by a crazy amount maybe? Seems like indonesian pros like Taufik can generate a lot of power even in disadvantageous positions where they can't get their arm and body behind the shot: that has to be wrist?
