Girls, good night! Question about cracks on nipples, I guess I don't know what it is... I think I know what cracks are and how to treat them and mostly at first this ?‍♀️ in general, nipple hurts, inflamed Montgomery gland or something like that, right on the areola, my son has teeth and it seems like he either scratched it or bit it, I go not hurting, should give the baby sparks from eyes so painful, I've been applying Purlane for 3 days but it doesn't go away.... There are no discharge, except for slight redness and when pressed it hurts ? Maybe someone had it? Or should I see a doctor?
