I switched to an interlocking grip last season, and it has helped so much! More control, less pain.
Working on overall hand strength can also help. I do some resistance band exercises that target the fingers and thumbs specifically.
Sometimes I wonder if this pain is just part of getting older in golf. Is it age, or technique? What do you think?
I think it can be both. But definitely, proper technique can help you avoid pain if you start young!
If none of this works, maybe it’s time for a golf thumb jersey? Just kidding! But really, let’s keep exploring options until we find what works best for all of us here.
