I don't know why but, recently I've began to experience some pain in my fingers when I make contact with the ball. I use a 4 3/8 grip, I always have, and its never bothered me before. I know I could be using 4 1/2 grip but, I don't. Anyways, you think it's about time I switch? Is there anything I can do to strengthen my hand? I appreciate your feedback.
