Im a 27 yr old women and have had sore, swollen breasts, ive never experianced this before, other than during and after the births of each of my children now age 4 & 8, i do massage my breast n do check regular for lumps, ive had the swelling n tenderness for at least a wk now, if im honest i love the fact the size of them has changed as after my children i dropped from a c-cup to a-cup n did lose alot of weight 2yr ago after i found my partner was cheating on me, so as you can imagine it made me lack confidence with the flat chest just puzzled as to why its started all of a sudden. There is also no chance of pregnancy as im single an havnt had sexual contact with anybody.
