Hello Doctor, I Am A Tennis Player And Have Come

Hello Doctor,
I am a tennis player and have come up with a sore elbow with mild pain. I've been icing it periodically and have taken naprasin effectively reducing the mild pain and am ready to continue playing. Do you have a recommendation that will prevent it from happening again, i.e. no topspin returns and a flat serve? How about wearing a band just in front of the elbow with pressure on the tendon?
Thank you for your reply, Ken
