i dont know why i am here, but anyway --> these are a result of estrogen and other such hormones (yes, boys have estrogen and girls have testosterone, just not as much in both cases...), i had this problem, and it should go away before you are 15 or so. they are temporary, they bothered me too but now they are gone. you don't need to do anything. i guess its just the changing from a child to a teen. good day!
