I'll tell you that pump is a killer! If you've been pumping a lot recently that could be it. Others have suggested bigger flanges, and yes, look into it, but even then my nipples were raw the entire time (I pumped exclusively for months). The nipple shields do help a lot. Also the soothie pads, which are expensive, so I only did it a few times but they helped a lot too. I think try the breastmilk remedy, air dry and get some nipple shields.
