It is considered to be lymph node enlargement. The human body's lymphatic system is spread throughout the body, including lymphatic vessels and lymph nodes, as well as other lymphatic organs such as the spleen, thymus, palatine tonsils (tonsils), and pharyngeal tonsils (adenoids). Lymph nodes are generally located along the lymphatic trunks in the body, distributed in clusters or lines, and connected to the lymphatic vessels. The lymph nodes are granular in shape and are generally difficult to feel under normal circumstances.
