Well, since very few people practice hard core nipple twister games before they have a baby I assume a lot of ladies also suffer from sore nipples when they start to breast feed…just simply because you are not used to somebody pulling and twisting your nipple for several hours a day.
My tip is organic LANOLIN and lots of air. After every breast feeding session apply Lanolin only to the nipple (not to the surrounding areola). If you already have sore nipples you will basically go through a painfull wend until it heals, but don’t give up! It will get better in up to 1 week and it is soooo worth it!

P.s. this is also a tip for men running marathon and forgot to tape their nipples.
