Enlarged tonsils, anti-inflammatory a month or swelling should be promptly to the otolaryngology consultation, identify the cause of the disease and then treat the cause. Commonly used treatments include medication, desensitization and surgery. The main reason why tonsils are still swollen after one month of anti-inflammation is that the patient’s immunity is weak, and the pathogenic microorganisms are repeatedly infected, or because of the poor drainage of the tonsillar crypts, the pathogenic microorganisms persist in the crypts. 1. Repeated infections of pathogenic microorganisms: because the patient’s immunity is weak, the treatment method, in addition to the use of amoxicillin, roxithromycin and other antimicrobial drugs, also needs to be used in conjunction with the use of desensitization therapy, such as the application of streptococcal allergens and vaccines for desensitization, and strengthening exercises to enhance immunity and other methods. 2. poor drainage of tonsil crypts: this cause is due to the physiological and anatomical structure, conventional drugs or other conservative treatment can not be completely cured, and subsequently produce recurrent inflammation or affect the respiratory and swallowing, may need to implement tonsillectomy. If the tonsils are still enlarged after one month of anti-inflammatory, it is best to go to the hospital in time, do not use drugs without authorization, so as not to cause adverse consequences.
