My breasts are really sore! over the past two years i've gained some weight and they seemed to grow! i'm a gg cup! please help?

Very common: That is very common as breasts get bigger. You're best off trying to lose the weight so the breasts can shrink down to a size without pain. For some women this can be difficult, but likely it's worth it in the long run because it's win/win. If you are at a normal bmi (19-24.9) then you may be a candidate for breast reduction surgery to help with the pain.
