Question
Thanks for your latest answer Warren.  I lost the link to reply to your answer, but I did get it.  As of right now, my thumb is doing much better inside the ball.  It is no longer tearing up the skin and I do not feel that I am squeezing the ball any longer.  
As for my hook... I can get this ball to hook quite nicely on the new lanes (where I got the ball originally drilled).  But at the older lanes that I bowl at, I have to slow this ball down immensely to get it to hook at all.  I understand that it is an oil issue, as if I throw my ball on the very edge of the right gutter, it hooks in (resembling a hockey stick) which I love the end result.  But it is so close that if I even fall a bit too far to the right, it goes into the gutter.  Is there anything I can do for my ball for a better hook in those conditions?  I read sandpaper but I am weary of doing that.  If I readjust my stance and mark for the older lanes, then I'll basically be throwing a straight ball.

Any additional advice.  Sorry for the rookie questions here.  Thanks for all of your help so far!  

Answer
Ren,
There are several ways to change the surface.

First, try not to let it change. Wipe the ball off all the time and clean it at the end of any outing.

Second, your local pro shop should be able to use Abralon, SAAIR, or 3M pads to freshen the surface or even rough it a bit for the older house for a nominal fee.

Lastly, using sandpaper, scuff pads, etc. could damage the ball or worse change the friction characteristics of your ball ruining how and where it bites on the lane (avoid this). Changing the surface seems easy, but I can't tell you how many bowlers have tried to do it themselves and ruined balls. Ask your favorite driller to help you, and have them explain some of the options and they may (safely) help you learn the tricks and techniques. Thanks for the questions.
