Hello. DD has started puberty and has breast buds. This morning she has woken up with a sore breast on one side. This has now become hot,slightly red and slightly swollen and very painful..Does anyone have any idea what his could mean? Could it be infected and if so could it wait till tues or should I take her to get it looked at tomorrow? I will of course reassess tomorrow but I am quite worried and would be really grateful if anyone has any ideas or experience. I have given her ibuprofen.
