Try to massage your breasts before pumping, or if you have a manual pump you can try expressing in the shower, warm water usually helps your breasts "let go". If they're sore frozen cabbage leaves are great for easing the pain. And nurse as much as the baby needs it, after a while they shouldn't be enlarged. Good luck momma!
You can use a warm washcloth on them and try hand expressing enough that she gets a good latch. I know it hurts, but you can do this..
