Sakit dan gatal bila ditekan tu memang common la among nursing mums, tapi sebab nak pastikan it's nothing serious, better check with your doctor or lactation consultant cepat-cepat, could be blocked duct, small cyst, or something yang boleh easily sorted. A few of my mum friends had similar benjolan yang hilang sendiri after they got it checked, some kena massage atau kena treatment sikit je dah okay. Jangan worry sangat dulu, tapi don't leave it hanging lama-lama sebab payudara kat stage nursing kena monitor closely.
