Hi, Im thirteen and since a few years ago Ive noticed that my left breast is larger than my right, which I know is normal already. I've also noticed though that my left breast is more sensitive to the touch than my right, and when I say sore I don't mean a throbbing pain, but it simply feels sore when I touch it or apply pressure. When I feel both breasts I don't feel anything irregular other than something I find that's in both but in (once again) my left it feels a bit lerger aswell. My sister says it's the same for her and that's it's normal but she doesn't contemplate it seriously. It's nerve-racking and from your knowledge, is it normal...?
Signed, Michelle
