So much pain! Help!!

I'm only four days in and I'm in so much pain! I know it's normal for your nipples to be really sore. I saw my nurse today, she gave me an A+ for my breast feeding technique and the amount he's been eating ( or the amount of frequent poops and pees I've been lucky enough to receive) but I've gotten to the point where I'm in so much pain and I just want a small break for a feeding or two, I haven't pumped yet, I'm thinking about giving my baby formula for just one feeding. My SO is worried that it's too early and that we'd have to teach him how to take the bottle, or that he'd prefer the bottle more. Any suggestions? I have also been putting nipple cream on almost after every feeding.
