Blocked milk with hard lumps is mostly due to milk stagnation and narrowing of the milk ducts, thus blocking the breast, which can be relieved by partial physical therapy and lifestyle adjustment. If there are symptoms such as swelling and pain in the breast, fever and chills, then acute mastitis is considered to have occurred. Press the breast in the direction of the mammary gland ducts from the periphery to the nipple to force the milk to drain. At the same time, you can also massage the corresponding acupuncture points of the breast to give some stimulation; 3. Sucking: After the hot compress and massage, the hard lump can be significantly reduced, at this time, you can let the baby suck or use a breast pump to help eliminate the milk. Timely medical treatment: 1. Medication: If the stagnation leads to inflammation and infection, redness, swelling and pain of the breast, oral antibiotics such as cefradine and amoxicillin should be taken under the guidance of a doctor to control the infection; 2. Physical therapy: Low and medium frequency treatment of the breast can be used to promote local blood circulation and reduce swelling and pain; 3. Surgery: If the ducts of the breast are blocked, they can be unblocked through lactoscopy. If an abscess has formed, incision and drainage are required if necessary. In addition, during breastfeeding, you should pay attention to a balanced diet and eat more soups. Keep your breasts hygienic to avoid the accumulation of bacteria in the nipples, which can cause mastitis and even affect the health of the fetus.
