With DD, they cut me (medically necessary) and it took 2 weeks for the cut to heal plus over 3 weeks after that before we were able to break the scar tissue down enough for sitting, large movements, and (ahem) more fun activities to not be painful.
With DS, I tore. It was enough of a tear that it needed to be stitched. That took about a week and a half to heal, but I was up and moving fairly regularly within a week. There was very little scar tissue to break down and I was feeling pretty darn normal within 2 weeks from the birth. In comparison to the episiotomy, it was a night and day difference.
I don't know if this is something you'd be willing to try, but my midwife suggested running a capful of hydrogen peroxide down external part of the wound one or two times a day, then rinsing off with water, and letting it air dry. It seemed to help me greatly.
