The PSO will mark the angles of the thumb on both sides and remove some material from the thumb slug. Then he'll smooth it out with a sanding tool. Most times that's all that's necessary.
I'll take it out on the lanes for a game or two to get a feel for the fit once my hand begins to warm up and often swell a little bit. I may ask the PSO to remove a little more so that again there are no sticking spots.
Finger holes are usually much more tight than the thumb. To obtain a good release your thumb must exit the ball first; therefore, it likely doesn't need to be all that tight. If it gets loose, you can always add white tape on the pad side of the thumb hole or black tape on the back side hole. Of course, I use several layers of white tape on the front of the thumb hole primarily down further to have the tip of the thumb to sit on and use some Teflon clear tape on the back of the hole to get the thumb out quickly.
Try visiting your pro shop and telling him what you're experiencing. He should get you fixed up in a jiffy!
