How deep can a wound on your left side go before hitting an organ?

I'm trying to figure this out for a story I'm writing. In the story, one of my characters gets a piece of shrapnel stuck in his waist right about an inch above his hip bone. When medics try to go in and get it out, it instead goes in deeper. What I'm wondering is, how deep can that piece of shrapnel go before it hits an organ, and would it be painful.
