i am have an issue with tendinitis at the base of my thumb, i can actually move the tendon from side to side. Sometimes when i come out of the ball i get a intence pain up my thumb......i've had 2 cordozone shots into my thumb , which is only temp. relief.....my dr has refered me to a plastic surgen so i will see whats up soon..................but she had told me to stop bowling, i told to her she's crazzy......so i am thinking of getting at least one of my balls checked out an possible redrilled with new pitch/span.
PEACE
