UPDATE Hi everyone, I have been struggling with a great deal of pain for sometime now on and off for about 5 years in my wrist which has unfortunately gotten worse and started to impact how I live my day to day life away from tennis. Along with guidance from my family, sponsors, coaching team and surgeons I have decided to undergo an operation to hopefully fix the issue permanently ! This is a decision that I tried to postpone for a long long time but recently it's been too much to allow me to compete at the level where I belong. I will miss the next few months but i'm confident that this will be a catalyst when looking back in a few years. Thanks for reading J
