I'm naturally born to write with my left-hand. However, whenever I play racquet games, I use my right hand. Similarly for soccer, I use my right leg (though I have since trained my left leg to be both-legged). However, due to a shoulder-dislocation injury that I suffered years ago, the joint area of my right shoulder 'pops'/'slips' off rather easily. Because of that, I'm considering switching my tennis play from a right-handed play (which was what I've been doing since I played tennis) to a left-handed play. Any advice on if it's advisable and if it's very difficult (perhaps impossible) to attain the level of my right-handed play?
