Women with swollen axillary lymph nodes during lactation can be treated differently depending on the specific condition of the patient. First, if the lymph nodes in the armpit are enlarged during breastfeeding, it is a reactive enlargement caused by breast enlargement and dilation of milk ducts, which will not cause pain and other symptoms to the patient at this time. The enlarged lymph nodes can gradually shrink and return to normal after the lactation period is over, so no special treatment is needed and close observation is sufficient. If the acute mastitis during lactation causes swollen axillary lymph nodes, the patient needs to actively strengthen anti-infection treatment, and the acute inflammation can be topically applied with golden yellow san ointment and fisetail ointment to promote the absorption of local inflammation. After the inflammation is controlled, the swollen axillary lymph nodes can subside on their own and do not need to be surgically removed.
