If there is milk stagnation during breastfeeding and hard lumps remain locally, you can use hot towel compresses, hot water showers on the breasts, and using a breast pump to empty the breasts to unclog them. 1. Apply hot towel: If there are hard lumps in the breasts with pain symptoms, use hot towel to repeatedly apply hot compresses to the local hard lumps to help dredge the mammary glands. 2. Shower the breast with hot water: massaging the breast while showering with hot water is conducive to the flow of milk, which is beneficial to the unblocking of the mammary glands. 3. Empty the breasts with a breast pump: if the patient has milk knots, you can use a breast pump and massage the breasts while sucking. If the milk knot is not very serious, the use of breast pump can unclog and eliminate the hard lumps. It is recommended that breastfeeding mothers be unblocked under the guidance of a doctor so as not to aggravate the symptoms and lead to septic mastitis and other diseases.
