Introduction
In general, axillary lymph node enlargement may be caused by factors such as puberty development, recent vaccination, drug reactions, mastitis, or systemic lupus erythematosus. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. In daily life, one should avoid excessive fatigue and chronic sleep deprivation to prevent decreased immune function, which could worsen lymph node enlargement.
Under normal circumstances, swollen lymph nodes in the armpit may be caused by factors such as puberty development, recent vaccination, drug reactions, mastitis, or systemic lupus erythematosus. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:
1. Puberty Development
Hormonal fluctuations during puberty may stimulate the lymphatic system, leading to mild swelling of the lymph nodes. Usually, no specific treatment is required; regular check-ups to ensure no other abnormalities are sufficient.
2. Recent Vaccination
After vaccination, the body generates an immune response that activates the lymphatic system. As part of this immune response, lymph nodes may swell, manifesting as enlarged axillary lymph nodes. This type of swelling is typically temporary and can be relieved with cold compresses.
3. Drug Reactions
Certain medications may stimulate the immune system or trigger allergic reactions, causing lymphocyte proliferation and resulting in swollen axillary lymph nodes. In such cases, the responsible medication may be discontinued or the treatment plan adjusted under a doctor's supervision.
4. Mastitis
Mastitis may result from bacterial infection. When the body experiences an infection, lymph nodes—being part of the immune system—enlarge and produce more white blood cells to fight the infection, leading to the aforementioned symptoms. This may be accompanied by fever, pain, redness, and swelling. Treatment may include medications such as amoxicillin capsules, cefixime dispersible tablets, or roxithromycin capsules, as prescribed by a doctor.
5. Systemic Lupus Erythematosus (SLE)
Systemic lupus erythematosus may be triggered by genetic, hormonal, or other factors. The autoimmune response associated with SLE can lead to increased production of white blood cells within the lymph nodes, causing them to enlarge—commonly observed as swollen lymph nodes in the armpit. This may also be accompanied by joint pain and swelling, fever, and other symptoms. Under medical supervision, medications such as cyclophosphamide tablets, methotrexate tablets, or prednisone acetate tablets may be used to alleviate symptoms.
In daily life, excessive fatigue and chronic sleep deprivation should be avoided to prevent decreased immune function, which could worsen lymph node swelling. Additionally, spicy and irritating foods should be avoided, as they may stimulate the lymph nodes and exacerbate the condition.
