hello dear doctor,

i have always had thumb friction when playing different sports, like tennis. I would develop what is called "tennis thumb". but for many years I also played billiards game and surprisingly also I am getting thumb friction with the grip when I hold and play with the billiards cue.

two days ago i practiced many long hours and unfortunately well the skin on the flexing point of the thumb, just above it, got pretty damaged (skin). So I'm trying to find a good solution so that the friction will not affect that part of thumb anymore.
