Boob problems

Niki
So I have somewhere between DD and DDD bra size. I've always noticed that when I get turned on or they get stimulated, the area around my nipples gets little tiny puffed up patches of skin. However, for the past two weeks or so those patches have just been there and they itch sometimes even though I have not been aroused. My boobs in general have been sore more often and sometimes get a small shooting pain through one of them. Does this happen to anyone else? Would yall be concerned?
