Nipple pain and discomfort during breastfeeding can be attributed to two main situations: first, when breastfeeding, due to incorrect breastfeeding posture, the baby only sucks partially on the nipple, resulting in damage to the nipple mucous membrane and breastfeeding pain. At this time, you should adjust the breastfeeding posture, let the baby suck all the nipple and part of the areola, and at the same time, gently massage the breast with your hand to assist the baby to eat milk. Secondly, when the baby sucks too much or bites the nipple, the nipple can be cracked, resulting in painful breastfeeding. At this time, the nipple and areola can be sterilized with vital iodine, and local erythromycin ointment or Pepto-Bismol ointment can be applied, and the nipples can be washed before and after breastfeeding, so as to maintain the cleanliness of the nipples. In conclusion, if nipple pain occurs during breastfeeding, you should go to the breast surgery department or general surgery department of a regular hospital in a timely manner to clarify the cause of the nipple pain and actively cooperate with the specialist for treatment, do not believe in folk remedies and unauthorized use of medication, so as not to cause serious clinical complications.
