Most get a blister where they place their hand on the grip, but I did not. I hit more balls than I usually do the other day and got a blister on my right hand (dominant hand) on the right side of my ring finger (the joint above the knuckle). I use an overlap grip, and I was guessing that my ring finger rubbed against my index finger (left hand). Any thoughts on how this happened and how I might prevent another? I know taping might be an option, but would prefer not to.
