Postpartum hulk rage?

I had my little boy on Sunday and have since turned into a moody monster. I got all this literature on postpartum depression, but no one mentioned post baby hulk rage. Of course, part of me thinks my husband just might actually be that incompetent- he smacked me on the ass when I bent to straighten my sock just a few hours after an unmedicated birth with a 2nd degree tear. I went off on him so bad a nurse came to check on me. He's done a handful of other, less inconsiderate things, but each one makes me want to smack him! No one else seems to be bothering me, though. No animosity for my new baby or my 3yr old- just the asshole I married. Should I be worried about this developing into something worse? Should I call my OB? Anyone else experience this?
