Ay oo, ganyan din nangyari sa akin nung nagsimula akong mag-breastfeed, super sakit talaga ng cracked nipples at ang dark part (areola) can get really sensitive, lalo na kung maliit lang pero intense ang pain! Have you tried Mama's Choice Nipple Cream? A few of us in our mum group swear by it kasi pregnancy-safe at breastfeeding-safe talaga, at sobrang effective sa healing ng cracks at soreness. But mamsh, para sure na okay lang yan at hindi something else, better check with your OB or LC (lactation consultant) if the pain doesn't improve in a few days, para may proper guidance ka on latch din, sometimes it's a latch issue na pwedeng i-adjust.
