There are many reasons for breast tingling while breastfeeding, and there are two main ones. The first is cracked nipples and split nipples caused by incorrect breastfeeding, which causes tingling in the breasts. The other cause is the accumulation of milk in the breasts, which is often referred to as milk retention, causing tingling in the breasts. The main treatment for tingling caused by cracked nipples is to apply milk to the nipple after each breastfeeding and leave it to dry naturally. Always wear loose cotton underwear and keep the nipple area well ventilated. If necessary, the area can be exposed to sunlight to promote healing. If redness or swelling occurs, use iodized povidone or erythromycin ointment. After using this, always wash the nipple with warm water before breastfeeding. Another tip is to breastfeed with the healthy side first, that is, the breast that has no stinging sensation, and then with the breast that has stinging sensation, which can reduce the baby’s sucking force and alleviate the pain. If the breast pain is caused by the accumulation of breast milk, first of all, we should go to the hospital for ultrasound examination to clarify the degree of accumulation of breast milk, and then we can give cold compresses. Many people apply hot compresses, but in fact, hot compresses will aggravate the symptoms. Hot compresses will promote the secretion of milk and aggravate the tingling of the breasts. Cold compresses can reduce local milk secretion and alleviate the symptoms. You can use appropriate techniques to push the breast to promote the discharge of milk, that is to say, the milk ducts do not pass before the progressive accumulation of milk, and this pain, and another is to encourage the baby to suck on this side of the breast, by the baby’s sucking force will be discharged milk.
