Many mothers will encounter this situation, a tingling pain in the breast after breastfeeding, as if it hurts like being stuck by a needle, which is mostly a phenomenon of breast duct spasm. For its treatment, before breastfeeding, you should gently squeeze the areola to cause the lactation reflex, and then let the baby suck the rest, and do not breastfeed for more than 20 minutes each time. Insist on doing chest enlargement exercises such as push-ups and physical exercises such as swimming to make the chest muscles developed and strong, enhance the support of the breasts, thus alleviating breast atrophy and preventing breast sagging. Insist on massaging for 10 minutes after feeding, and wash your breasts with water every day to keep them clean. Note also that you must keep your breasts clean to prevent germs from infecting your nipples. Also pay attention to the scientific and correct knowledge of breastfeeding, and pay attention to the fact that the baby must hold the nipple and areola together in the mouth when sucking. Proper breast massage and health care can prevent the occurrence of milk duct cramps.
