I recently got back into bowling over the summer. I injured my knee in the summer of 2011, in my first league back after not bowling since 2008. Essentially I haven't bowled a full season since 2008.
After such a long break, I decided to have my span remeasured, and bought 3 new balls (med/light/spare). However since getting the balls, my wrist hurts after a few games. The outside/pinky side of my wrist hurts right at the joint for a few days after bowling. Imagine unlocking your front door, the wrist hurts when I do a key turning motion. Bowling with my old gear for several weeks didn't cause any pain, and this started the week I had the span remeasured.
A few things changed. First, the middle finger span remained the same, but they shortened the ring finger by an 1/8". Now both fingers are the same length. I also switch from urethane thumb slugs to the sized vinyl thumb inserts. I love the thumb change, as all my balls feel exactly the same now. I also dropped from 15 to 14 pounds. With the old gear.. no wrist pain. With the new gear... wrist hurts for a few days each time I bowl.
Is this just coincidence that my wrist started hurting now, and several weeks of no pain with the old balls? Or is the span, thumb, or weight change to blame? Leagues start in 2 weeks, and I would like to have everything fixed before then. Any advice would be appreciated. Thanks.
