Quoting Kaelyn & Kamron's Mommy:" mostly the nipple, plus they're scabbed over!"
It could be the latch, but some nipple pain can be normal. When you get your little one to latch, squeeze the areola down like a hamburger and then shove as much of the areola and nipple into baby's mouth as possible. That was my trick. I need to take a picture of it so it's easier for women to understand lol. It's hard to describe, but I hope that helps.
For the scabs, try expressing milk before feedings and rub it around nipple/areola. After the feeding, express more milk and put it on your breasts, then let your nipples air dry.
You can also try things like lanolin but a lot of babies aren't big on the flavor.
