The lymph nodes in the armpit should not be massaged. If the lymph nodes are swollen, it is not possible to eliminate them by massaging them, but the external stimulation can cause them to get bigger and bigger. If the swollen lymph nodes are accompanied by pain, it is considered to be caused by bacterial infection and needs to be treated with oral antibiotics, such as cefixime or levofloxacin hydrochloride, which are commonly used. If the swollen axillary lymph nodes are not accompanied by pain, it may suggest that it is caused by tumor metastasis, which can lead to tumor spread if massaged. If breast cancer is the most common cause of axillary lymph node metastasis, you should check the internal breast for nodules and lumps, and if necessary, perform breast ultrasound or mammography to check.
