It is not recommended to stop lactation during acute mastitis. Because breast milk is the best culture medium, bacteria have already caused local inflammatory invasion. If lactation is stopped at this time, the milk will accumulate in the milk ducts, leading to a large invasion of bacteria, which can eventually cause cellulitis. If untreated, it may lead to an abscess and then septicemia. Generally, for acute mastitis, breastfeeding is stopped, local heat application is necessary, and then a lactation masseuse or family member should be found to completely empty the residual milk, which needs to be done daily. Then, the use of antibiotics can achieve the purpose of treatment.
