The difference between enlarged and swollen lymph nodes mainly includes the following aspects: 1. The clinical manifestations of the two are different. Lymph node enlargement is simply the shape of the lymph node becomes larger, without symptoms of redness, swelling and pain, while lymph node enlargement is mostly accompanied by redness, swelling, pain and other inflammatory manifestations. 2. The causes of lymph node enlargement and enlargement are different. The causes of lymph node enlargement mainly include inflammatory stimulation, tumor stimulation or immune response of the body. The cause of enlarged lymph nodes is mainly due to inflammatory stimulation, mostly due to acute lymphadenitis. 3, there are differences in the treatment of the two. Lymph node enlargement requires clarification of the cause of lymph node enlargement and symptomatic treatment, resulting in acute lymph node inflammation, which mostly requires treatment with antipyretic and detoxifying drugs. Enlarged and swollen lymph nodes are common clinical diseases in general surgery, and the diagnosis is mainly based on typical clinical symptoms and relevant auxiliary examinations, including ultrasound. If the cause of lymph node enlargement is difficult to be determined, biopsy should be considered, i.e. lymph node removal followed by pathological examination for clarification.
