sounds like a crack to me (both my nips looked like this for the first 5 weeks). honestly, no matter what i put on them (lanolin, motherlove nipple cream, polysporin) and no matter how i treated them (airing them out, no bras/shirts, warm, moist compresses, etc.) they took their own time to heal. sure, all that stuff was comforting to me emotionally, but physically, i don't think it made a difference.
some women have great success with ointments and whatnot, and some don't. i know you've been having quite a time with soreness, thrush, etc. (been reading your other posts), and i think you're doing an awesome job, mama! you might want to try some of the suggested crack treatments, but then again, you may want to just leave it alone and let it heal on its own. it will, over time.
hang in there!
