For the last few months about 2-3 times a month I wake up with very sore breast that are much larger than normal. In the mirror I can't complain, they are perky and full. Yet by mid day they are back to normal and achy for about 2 days. The majority of the soreness radiates from the outsides of both breast and the under side into the middle. I am 26, not pregnant and not close to starting my monthly.
