Using yonex 880 soft my arm never hurt when I switch to another multi and I have tried over 15 of them the inside of my elbow aches for days then it goes away. is it golfers elbow. My arm has lost no strengh it does not hurt to play its after it just aches after playing. Do you think its just shock hurting my arm. I use a PK 5g anybody else have this weird problem. They stopped making the 880 thats why i need to switch.
