If you experience pinching pain in the breast during breastfeeding, it may be caused by milk duct spasm. In this case, you need to find a professional doula to unblock the milk ducts and empty the milk to prevent the occurrence of acute mastitis. If the breast pain is more severe and there is redness and swelling, there may be acute mastitis. This condition requires prompt examination at the hospital. If it is determined to be acute mastitis, the breast needs to be emptied and treated with active antibiotics. Temporarily stop breastfeeding on the affected breast during the treatment period and use a breast pump to suck out the milk and empty the breast to facilitate the treatment of mastitis. If the breast swelling and pain are more severe, you can take hot compresses to relieve the symptoms. Allowing the baby to suckle regularly during breastfeeding and emptying the breast in time can prevent the occurrence of mastitis.
