Yeah, I had that, too - my hands hurt and got marked for the first few workouts, but then it went away.
And I also had that, especially when I noticed I could grip the bar so much narrower with thumbs-around and thought that would be better because of more upper-back tightness. But I found that taking a slightly wider grip helped. Maybe the larger the lifter, the wider the grip?
Jesse Norris narrow grip
Garrett Blevins moderate grip
Dennis Cornelius, wide grip
Big Ray, max grip
