The most common cause of swelling and pain in the armpit is enlarged axillary lymph nodes, which is common in patients with acute mastitis, especially during breastfeeding, and may also manifest as breast pain and fever, for which systemic anti-infective treatment is recommended.
At the same time, local hot compresses can be used to improve microcirculation and reduce local symptoms to a certain extent.
In addition, there are patients with malignant tumors, especially breast cancer, that are prone to axillary lymph node metastasis, and some patients with occult breast cancer have no obvious mass in the breast on clinical examination, but have enlarged and even painful axillary lymph nodes, which is a manifestation of advanced stage.
Particularly in patients with pain, it is important to be vigilant and not to be careless, and to go to the hospital as soon as possible to identify the cause and target treatment.
