It gets better. I hurt so bad when I nursed, but it got so much better after a while. I nursed until my son's 1st b-day when he just decided he was finished (very difficult for me but no weaning process). Anyway. . .Just hang in there. Use some of those cold packs when you can and see if it helps. You may need to pump in between feedings to releive some of the soreness. You may just be producing a lot of milk and need to get rid of it more often than your baby is eating. That's good, though, because then you can store it away for later.
