I have cracked nipples and feeding hurts like hell. I have managed to get one side so that it is not so bad. The other is still total agony. I wonder if I should rest that side or not. The last time I tried to do that it became engorged and I got blocked ducts even though I was pumping every time I feed from the other breast. It also didn't seem to help any in the long run so part of me thinks that it isn't really worth it. It's very painful on that side though.
