Milk knots are usually caused by the accumulation of milk due to the failure to empty the milk in time. The first step is to empty the milk in the breast, then apply local heat and massage to promote local blood circulation to unblock the knot. If the condition is serious, medication can be used to treat the condition, and if the patient has symptoms such as redness, swelling, heat and pain, it is recommended to seek medical attention in a timely manner. 1. Emptying milk: you can increase the number of times your baby sucks, allowing your baby to suck frequently on the breast with milk knots. You can use a warm towel to apply hot compresses to the breast with milk knots, which can improve the milk knots to some extent. However, it should be noted that if inflammation occurs in the breast, such as in the acute stage of mastitis, hot compresses are generally not recommended to avoid spreading the inflammation. 3. Massage: You can ask a professional masseuse to help untie the knots by using your index finger and thumb to lift and pinch the nipple to relieve the pressure in the areola area and push from the root to the nipple to promote milk discharge. You can also use massage while breastfeeding, squeezing and massaging from the milk knot to the nipple, which is also beneficial to milk discharge. 4. You should go to the hospital in time and use medication under the guidance of the doctor. The initial stage can be treated with penicillin, those who are allergic to penicillin can use erythromycin, and those with more serious symptoms can use tetracycline, metronidazole and other drugs. You should pay attention to a light diet, avoid spicy, greasy, cold and stimulating food, drink more water, eat more fresh fruits and vegetables, have a good routine and get enough sleep, all these are good for relieving the milk knots.
