Lymphatic follicles, like lymph nodes, exist in every person. Lymphatic follicles are lymphatic tissues in the pharynx, located in the posterior wall of the pharynx, and together with the pharyngeal tonsils, palatine tonsils, lingual tonsils, pharyngeal bulbar tonsils, and pharyngeal lateral cords, they form the endopharyngeal lymphatic ring, which is a peripheral immune organ and participates in immune functions. When the pharynx is stimulated by various pathogens or the body is invaded by pathogens, the lymphatic follicles, like the tonsils and the lymph nodes of the body, will grow and swell, and when the pathogenic factors subside, the lymphatic follicles will shrink, but some of them may persist for a long time. If lymphatic follicles exist for a long time, do not be overly concerned and do not need any treatment, eat less spicy and irritating food, quit smoking and alcohol.
