Introduction
Swollen lymph nodes in the neck due to "excess internal heat" (a traditional concept) may result from inflammatory changes caused by viral or bacterial infections of the lymphatic tissue, or possibly other causes such as tumors. Antibiotics may be taken under a doctor's guidance. In addition, allergic reactions can also lead to swollen lymph nodes; avoiding allergens promptly can help relieve symptoms.
Swollen neck lymph nodes due to "heatiness" (a traditional concept referring to internal heat or inflammation) are usually caused by inflammatory changes following viral or bacterial infections in the lymphatic tissue, but may also result from tumors or other causes.
1. Viral
Viral lymphadenopathy is typically caused by infections such as cytomegalovirus (CMV) or Epstein-Barr virus (EBV), and is often accompanied by symptoms like pain and swelling. Patients should follow medical advice to treat the underlying cause. For example, CMV infection can be treated under a doctor's guidance with medications such as ganciclovir dispersible tablets or valacyclovir hydrochloride tablets, while EBV infection may be managed with Pudilan oral liquid or ribavirin granules to relieve symptoms.
2. Bacterial
Bacterial lymph node enlargement is commonly associated with symptoms such as fever and fatigue. When lymph nodes swell due to bacterial infection, the overlying skin may become red, swollen, tender, and warm. Under medical supervision, patients may take antibiotics such as amoxicillin capsules or cefaclor capsules.
3. Tumor
If the swelling is caused by a tumor, the lymph nodes may continue to enlarge progressively. In such cases, it is important to seek medical evaluation to identify the underlying cause.
In addition, allergic reactions can also lead to lymph node enlargement. Avoiding known allergens promptly can help alleviate symptoms.
