Re: sore breast again
Pus? What color is it? A lot of mamas mistake the very watery, very clear milk that comes from a plugged duct for pus. Could that be what you're seeing? Regardless, it is fine to nurse from that side. In fact, it is desirable: the more thoroughly you drain the breast, the less chance there is of getting any infection setting up in that plugged area.
Blisters are generally caused by the baby's latch. When the baby's latch isn't perfect, or he's playing around a lot (which often happens when the baby is teething), that's when you get blisters. My gut feeling- unsupported by knowledge- is that blisters are actually callouses caused by irritation to the skin.
