What should I do about swollen submandibular lymph nodes?

When submandibular lymph nodes are enlarged, the underlying cause should be identified. Possible causes include inflammation, lymph node infection, malignant lymphatic diseases, or other malignancies such as leukemia and AIDS. For this condition, the following measures can be taken: 1. Observation and rest: If caused by inflammation or mild infection, the condition may resolve spontaneously with adequate rest and observation. 2. Seek timely medical attention: If the enlargement is significant, persistent, or accompanied by symptoms such as pain or difficulty swallowing, immediate medical consultation is recommended. Diagnostic methods such as ultrasound or biopsy may be used to determine the cause. 3. Targeted treatment: Based on the underlying cause, doctors may prescribe antibiotics, antiviral medications, or immunomodulatory agents. Traditional Chinese medicine may also be considered for regulation. 4. Adjust lifestyle habits: Maintain good oral hygiene and avoid consuming spicy or irritating foods to reduce inflammatory stimulation.
