DD1 turns 11 in April next year, so she's at the age where everything is starting to change & develop. So this could be normal, but I didn't experience it, so I'm not so sure.
She has a very hard lump, behind her nipple. Its pretty painful too. i remember having some pain at that age, but no lumps. Its about pea size.
Is that normal or should it be checked out? I told her we'd leave it for a few days & see what happens, but I need reassurance
