During the postpartum breastfeeding period, some mothers may experience skin itching, which mainly depends on the cause. It is generally due to changes in physical constitution and other factors, such as sweat rash, prickly heat, and unexplained papules and hives. During breastfeeding, the most common cause of skin itching is sweat rash. Sweat rash occurs when the body sweats after childbirth, and patches appear in the skin folds, sometimes merging into a large area. At this time, it is important to keep the skin dry and topical antibiotics can be used for local application. (Please use medications under the guidance of a doctor.)
