I've been getting the painful kicks too -- so much so that she wakes me up at night and I sit bolt upright in bed. I think placental position makes a big difference in how much you feel. With #1, the placenta was attached to the front wall of the uterus, and while I could definitely feel movement, it wasn't of the magnitude that I feel this time. With this pregnancy, the placenta is attached to the back wall. I started feeling movement SO much earlier, and the type of kicking is so much more intense.
