I've lately had some pain in my left thumb after playing a lot of bar chords. I often have my thumb pointing to the left while doing bar chords and I press down on the neck for more leverage. I have rather large hands, so I kind of slant my fingers to compensate and have more control. If there is a way to easily put less pressure on my wrists when I play, I would really appreciate it. I'm only 21 years old, so I have a long life ahead of me. I don't want to have issues that prevent me from playing my guitar in the long term.
