Arm Problems: I have made adjustments in my game and equipment including different string set-ups, arm friendly frame, rest, ice and technique adjustment. While there has been significant improvement, my arm still gets sore and fatigues easily. The soreness and fatigue is only after serving and in my bicep and tricep areas. I thought I would go all in and try some compression sleeves. Has anyone had any luck with them? Any brand suggestions? Are the running ones good enough, or do you have to get ones designed with tennis in mind? Or is it a little bit of nonsense?
