Lymph nodes often shrink on their own as an infection recedes, thanks to the body's natural defense mechanisms, and do not require specific treatment in most cases. However, untreated or progressive infections can lead to sepsis, potentially advancing to serious complications such as organ failure. Furthermore, signs such as enlargement, change in shape, or increased wall thickness of lymph nodes can indicate malignant diseases associated with the lymph node. Therefore, it is essential to consult a physician for accurate diagnosis and appropriate treatment planning.
