A brief YouTube Shorts clip by Lauren Bateman offering a quick guitar technique tip to reduce thumb/palm pain: avoid squeezing the thumb against the back of the fretboard and instead practice playing open chords without using the thumb, relying on slightly more downward finger pressure so chords ring clearly.
Quick tip for those of you suffering from thumb pain when playing the guitar, a lot of times what happens is people press the back of the fretboard way too hard with their thumb and they get a lot of pain here in the palm of their hand. My recommendation to people is play your open chords and take the thumb out of the scenario so you can play your chords without using your thumb at all. Okay. And you can still get them to ring through perfectly fine. You can see my thumb back here not doing anything. So get used to using a little bit more downward pressure to play your chords instead of squeezing your thumb on the back of the fretboard.
