Small particles in the throat may refer to the lymphatic follicles in the throat. Lymphatic follicles are lymphatic tissues in the human body, which are widely distributed in the throat and the root of the tongue. Normally, lymphoid follicles are inconspicuous and scattered, with no surface congestion and a light red surface. Once the patient has chronic pharyngitis and acute pharyngitis and other pharyngeal infections, the lymphoid follicles will proliferate, hypertrophy, and behave very obviously, and most of the surface has a lot of exudation, even pus and other clinical manifestations, which is clinically referred to as lymphoid follicular hyperplasia. Under normal circumstances, patients with scattered lymphatic follicles in the pharynx do not feel anything and do not experience any discomfort in the throat. When lymphoid follicular hyperplasia is very obvious, patients may experience a foreign body sensation in the pharynx, a burning sensation in the pharynx, and an unpleasant sensation in the pharynx when swallowing saliva. In general, patients with chronic pharyngitis can apply pharyngolaryngitis tablets or take oral Chinese medicine preparations for pharyngitis to relieve pharyngitis symptoms and reduce lymphatic follicular hyperplasia.
