Chronic tonsillitis mostly has no obvious conscious symptoms, but may have a dry throat, foreign body sensation, etc. There is often a history of repeated acute tonsillitis episodes, and in children, excessive tonsillar hypertrophy may affect breathing and swallowing. On examination, chronic congestion of the tongue and palate arch, chronic congestion or scarring of the tonsils, caseous pus at the trap, and enlarged lymph nodes in the mandibular angle are seen. Pharyngeal disorders that need to be differentiated from acute tonsillitis include pharyngeal diphtheria, Winsor’s pharyngitis, mucocytopenic pharyngitis, ulcerative pharyngitis, and pharyngeal keratosis. Tonsillitis can cause a variety of complications, such as peri-tonsillar abscess, rheumatism, acute glomerulonephritis, arthritis, and myocarditis. Examination reveals congested and swollen tonsils, mostly with yellowish-white purulent discharge at the mouth of the trap, more so in cases of follicular suppuration, and small yellowish-white abscesses under the mucosa. The patient has swollen and painful lymph nodes in the jaw angle and elevated white blood cells in the blood. Pay attention to oral hygiene and develop good living habits. Take meals on time, drink more water, eat more green vegetables and fruits, do not favor meat, especially do not eat too much fried chicken and fish. Pay attention to the environment. In the summer, the temperature difference between the air-conditioned room and the outdoors should not be too large, the temperature should not be adjusted too low, generally not less than 25 degrees Celsius. When you want to go out, first open the door at the door to adapt to half a minute, and then go out. The air in the room should be kept fresh and circulating, and the relative humidity should be 45% to 55%. During the cold and flu season, if you have a red face and a slight cough, you can drink Pancreatin as a tea, which can play a preventive role.
