I'm a righty and when I bat, sometimes I get pain between my hand and my left wrist (see image). I think this is because my left hand grip is wrong/too stiff during contact, making my hand flex down into my wrist joint.

Am I supposed to loosen my left hand during contact? Or maybe turn left grip counterclockwise to let my wrist flex in its natural direction, if it needs to?

Thanks for any replies/advice.

Edit: Ok I think I figured it out. My old tennis swing was making me keep a stiff right hand grip through contact, but loosening my right immediately after contact is preventing me from turning the bat into my wrist.
