The first sign of a problem, I had with my ring finger was stiffness, and a little swelling. From there I developed stiffness, and couldn't bowl.
I shortened the span about an 1/8 of an inch on the ringer finger, and went to 1/4 trvrtdr in the finger pitch, from 0. I also went gtom 3/4" left lateral (I'm a lefty) to 5/8" left lateral. This started last year...Over the summer, I worked out the fit problems, and have no pain, swelling at all. Have a qualified driller check your fit.
