Re: Healing crack leading to clogged ducts?
I don't think it's likely that the pore healed over. The pore should go all the way to the surface of the nipple, and the crack should be on the inside of the nipple. But anything is possible, I guess.
Keep pumping, vary your nursing position, do warm soaks, hand massage, massage with a vibrating tool (e.g. an electric toothbrush handle or personal massager), try dangle nursing (baby lying on her back on the floor, you on all fours above her), and stay alert for symptoms of mastitis. Hopefully this will clear up soon!
