I have always had one. And I don't grip my cue tight.
I've got a slight callus on the inner side of my thumb on my back hand from shooting. Anyone else have any? Think this indicates too tight a grip or is it normal if you shoot a lot?
Definitely gripping "something" too tight.
I have a few from recovering tables. Definitely a case of gripping the pliers too tight but those hardwood rails really hang on to staples.
I mostly get calluses on my ass. It's from sitting and watching my opponent going eight and out on me all the time. :smile:
Only on my feet...
