The main manifestation of lymph node reactive hyperplasia is the enlargement of local lymph nodes, which may also be associated with painful symptoms. It is usually secondary to local tissue infection or adjacent organ lesions, and the patient may present with local discomfort, enlarged lymph nodes on examination, and mild tenderness. Irregular fever may also occur, accompanied by an obvious loss of appetite. The hyperplasia and enlargement of lymph nodes caused by simple inflammation can be improved by anti-inflammatory treatment, which can also be combined with local physiotherapy and hot compresses. For malignant tumors with secondary hyperplasia or enlargement of lymph nodes, there will be obvious symptoms of the primary disease, including pain and discomfort. For respiratory tract lesions, there will also be obvious chest tightness, irritating cough and coughing sputum, and digestive tract diseases will also show abdominal distension, abdominal pain, and even nausea and vomiting.
