I read in a baby book that warm salt water helps with the soreness..
Are your bras comfy? My nipples were getting very sore if I was not wearing a very supportive bra. Other than that I don't know.
Im having almost the same problem except mines feel more like a burning sensation..I found that heat packs or a warm rag really helps..hope it gets better!
Don't know if there's anything to be done :( I was terribly sore right off until maybe 10 weeks or so it gradually got better. I'm really enjoying the break right now because I'm sure it'll come back!
