A broken nipple usually heals on its own in about a week, but the exact healing time also depends on the severity of the break. Nipple breakage occurs most often during breastfeeding and is mainly caused by improper feeding positions coupled with delicate nipple skin. When feeding, you should choose a position that is comfortable for both mother and baby, and allow the baby to hold both the nipple and areola in the mouth, not just the nipple. Daily life advice to keep the nipple local hygiene and dry, to wear loose underwear, to reduce the friction on the nipple stimulation. Nipple breakage can be sterilized with povidone-iodine and then apply erythromycin ointment if necessary, but it is necessary to suspend breastfeeding on that side of the nipple first, and at the same time, attention should be paid to avoiding spicy and irritating food, quit smoking and limiting alcohol, in order to promote the early healing of the wound. The medication should be reasonably applied under the guidance of a physician.
