Thumb blister

I am developing a blister on the back of my thumb just below the knuckle.
I use trurbo switch grips. Main balls: Halo solid pin up and Astro Physics also pin up. Hammer palstic spare.
Our league shot 42 ft-- light oil and lanes burn up quickly.
I'm 7o years old--returning to bowling after 25 years and in about 6 months have my average back up to 187 to 195 in my 4 leagues.

Bact to the thumb. Is it probably release or gripping the ball wrong?
I do use a piece of white grip tape in the front of thumb hole because I find the switch grips a little smoothe and slippery.

Sounds like you’re bending your thumb, use tape to have a snug fit so you don’t grab it during your swing.
