Lymph node inflammation and pain need to go to the hospital surgery or internal medicine department as soon as possible to improve the relevant examination, according to the cause of treatment. If elevated white blood cells and neutrophils are found, it is often considered to be caused by bacterial infection, and antibiotics should be given to treat it. If a viral infection is found to be the cause, antiviral drugs such as ribavirin should be given for treatment, while Chinese herbal medicine can be used for better results. If the allergy is considered to be the cause, it is necessary to actively remove the allergen and take oral desensitizing drugs, such as cetirizine, etc. At the same time, it is necessary to increase rest and drink more water. In some cases, the tumor may be caused by malignant tumors, and the primary tumor may be removed, followed by lymph node dissection, and later chemotherapy.
