White dots on the nipples indicate blockage of milk ducts and milk stagnation during breastfeeding. You can apply local heat to the breast and massage the breast with the correct massage technique to speed up milk discharge. If the milk is still not emptied and the stagnation of milk is further aggravated, you will be prone to acute mastitis, which is characterized by redness, swelling, heat and pain in the breast, and fluctuating lumps can be palpated in the breast, which often requires surgery. Therefore, when there is a white spot on the nipple blocking milk, you should cooperate with the treatment of a professional physician and avoid blindly believing in folk remedies, which may lead to aggravation of the condition, and at the same time, you should develop good breastfeeding habits in your daily life and wear loose and breathable cotton underwear.
