Oral and throat blistering refers to lymphoid follicular hyperplasia in the pharynx, which may be triggered by chronic allergic pharyngitis, chronic simple pharyngitis, chronic hypertrophic pharyngitis, and atrophic and desiccating pharyngitis, and needs to be treated according to the specific cause. 1. Chronic allergic pharyngitis: avoid contact with all possible allergens and apply antihistamines, such as cetirizine and loratadine. Localized glucocorticoid therapy is also needed. 2. Chronic simple pharyngitis: generally can use compound borax and furacilin solution and other gargle care, can also contain iodine throat tablets and mint throat tablets and other drug treatment. 3. Chronic hypertrophic pharyngitis: Treatment of raised lymphoid follicles in the posterior pharyngeal wall can be considered, including cryotherapy, laser therapy and electrocoagulation. 4. Atrophic and dry pharyngitis: small doses of iodine can be taken or applied topically to promote the increase of mucosal epithelial secretion; ultrasonic nebulization can be used to alleviate the dryness; vitamins A, C, E, and B2 can be taken to promote the growth of mucosal epithelial tissues in the pharynx. The onset of the disease can be diagnosed by a doctor and then follow the doctor’s instructions to standardize the use of drugs and treatment. The use of these drugs carries certain risks, and it is recommended that the patient needs to be guided by a specialist.
