Depending on individual differences, the time when the swelling and pain of breastfeeding is most severe varies, with some women experiencing the most pain for 3-4 days, while some patients may experience peak pain for 5-6 days. The amount of milk is low in the early stage of lactation, but as women consume more food and soup, the amount of milk increases accordingly, which can lead to gradual swelling and pain in the breasts due to the inability to excrete. Some women may experience the most severe pain around 3-4 days, and even touch pain, while some women may breastfeed for 5-6 days, when the milk secretion reaches the maximum, which is the most painful period. Generally, after 7 days, the amount of milk secretion will gradually decrease and the painful breast symptoms can be gradually relieved. It is usually recommended that women can choose to take fried malt, vitamin B6 and other drugs to assist in returning milk, and to drink less soup and water in their diet and avoid excessive intake of meat foods such as carp, pig’s feet and fish glue.
