The main reason for this is that the patient’s resistance is relatively low, accompanied by chronic rhinitis, sinusitis, long-term bronchitis, pneumonia and other diseases of the upper and lower respiratory system, which are easily transmitted to the tonsils and lead to inflammation of the tonsils. The patient’s clinical treatment is untimely or incomplete at the onset of each illness, and the normal treatment of purulent tonsillitis takes about 1 week.
