The lymphatic system is distributed throughout the body, so lymph nodes are present in many parts of the body. Lymph nodes are mainly found in the neck, jaw area, armpits, abdomen, and groin. Abnormally enlarged lymph nodes or other conditions are most likely the result of an abnormal lesion in the corresponding area, which is an inflammatory infection. Usually, acute infections can cause swollen lymph nodes, but in some patients with chronic inflammation, the inflammatory stimulation can also cause local lymph nodes to swell. Therefore, once the phenomenon of local lymph node enlargement occurs, you should go to the relevant departments of the hospital for further examination and diagnosis, and then carry out targeted treatment according to the examination results.
