Breast tingling during breastfeeding needs to be differentiated in terms of location, whether it is the nipple or the breast. If you feel nipple pain first and then breast pain, it is possible that the nipple is cracked radiating to the whole breast, causing breast pain. If the pain is in the breast, you need to consider the following two situations: 1. When you first start breastfeeding, the breast has a lactation or discharge reflex or the sucking action of a small child, which may lead to a tingling sensation in the breast, this is normal and does not need to be dealt with. 2. It may be that the milk has accumulated, which then leads to a blockage in the breast and eventually develops into mastitis, in which case the milk needs to be completely emptied. If you have a fever, you also need to physically cool it down, drink more water, eat more high-protein, high-calcium, high-energy diet, pay more attention to rest and the need to keep your breasts clean and wear loose underwear.
