I've been having a sharp wrist(lefty) for a really long time. Over a year and a half. It's about the time i started taking tennis more seriously and played a lot more. I tried resting it for a month and iced it often but the problem still persists. I don't know if it's maybe my racket (first k90 now kblade both strung with PHT) but would like to receive some advice on another approach to properly healing my wrist Any help would be greatly appreciated THANKS!
