If you have a hard lump in your breast and it is painful, you should let your baby suck more on this side of your breast if it is early, so that the milk that has accumulated in your breast can be sucked through, which can reduce the painful feeling in your breast. If it is longer and the lump cannot be sucked, you should not let your baby eat the milk on this side. If you continue to eat, the milk has deteriorated and will affect your baby’s health. You should use a breast pump to suck out the excess milk inside. During this period, you can use hot towels to warm up the milk or massage it to promote milk discharge. Avoid stagnation of milk for too long, which can lead to inflammatory infections. However, if the time is too long, if there is an increase in body temperature, this is a sign of inflammatory infection. It needs to be treated with anti-inflammatory drugs in time to control the development of the disease. If the effect of anti-inflammatory control is not good, there is a possibility of softening or the temperature continues to rise, it is necessary to take surgical treatment and do drainage surgery to completely cure.
