Lymphatic follicles in the posterior pharyngeal wall are normal and do not require any treatment. Lymphatic follicles in the posterior pharyngeal wall are lymphatic tissue, just like lymph nodes, and the tonsils are also composed mainly of follicles. The lymphatic follicles in the posterior pharyngeal wall, together with the pharyngeal tonsils, lingual tonsils, palatine tonsils, pharyngeal tonsils and pharyngeal lateral cords form the endopharyngeal lymphatic ring, which together participate in the immune function. When the lymphatic follicles in the posterior pharynx are stimulated by various factors, lymphatic masses can be formed and the lymphatic follicles will subside after the stimulating factors subside. If it does not subside, there is no effect and no treatment is needed. Pay attention to dietary habits, eat less spicy and stimulating food, drink more water, and quit smoking and drinking.
