they're sensitive because they're growing Maybe starting a period...
when you enjoy your period your breasts tend to be sore. Plus, it is also probably growing anguish. It will go away, don't verbs The reason that they are sore and puffy is because they are growing. It's mundane. Try taking alive or something like that and try any icing them or putting a heating wad.
