There are a lot of vesicular bumps in the wall of the throat, mostly lymphoid follicular hyperplasia of the posterior wall of the pharynx, which often occurs in acute and chronic pharyngolaryngitis, postnasal drip syndrome, reflux pharyngolaryngitis and other diseases. 1. Acute and chronic pharyngolaryngitis: Bacterial and viral infections or stimulation by adverse physical and chemical factors can lead to edema and hyperplasia of submucosal lymphatic tissues in the posterior pharyngeal wall, resulting in the formation of lymphoid follicles. 2. Postnasal drip syndrome: when chronic rhinitis, sinusitis and other diseases recur, there may be excessive mucus and inflammatory secretions flowing back into the pharynx, and inflammatory factors stimulate the inflammation of the mucosa of the pharynx, resulting in the appearance of obvious vesicular bumps. 3. Reflux laryngitis: stomach contents and stomach acid reflux to the throat, corrosive stimulation of the mucous membrane of the throat, triggering lymphoid follicular hyperplasia. There are a lot of vesicular bumps on the wall of the throat, there may be other reasons, should be timely to the hospital, to identify the cause of the targeted treatment.
