I had cracked, very sore nipples for the first 3 weeks or so too. I used lots of lanolin all day. Since my nipples hurt when wearing a shirt, for a few days, I purchased those breast shells (medela) just so that my nipples would be "safe" from the clothes rubbing on them. I thought it helped with the healing. Also, the nurse at the hospital told me to use a bag of tea seaped in hot water and rubbed them on the nipples. It also helped w/ the pain. And like other pps, I just hung in there.
