E.B.
My breasts in general have been very dry this winter. I am still nursing my son, so I don't know whether it's the fact that they're exposed more frequently than in the past--but I've been nursing him through 2 winters, and I don't remember this. If you're nursing, or did nurse, I would not be surprised if there was milk expressed if you're pinching. I had my first son 5 years ago and have had milk ever since I was 7 months pregnant with him--never lost it between kids, or when I was pregnant. I simply put lotion on my breasts and it seems to help, but you seem like perhaps you're more concerned than that; if that's the case, I'd suggest taking it to your doc.
