The main symptom of tonsillitis is sore throat. Severe sore throat can affect eating and swallowing effort, so it is recommended to eat warm and cool liquid food and semi-liquid food, such as porridge, milk, soy milk, noodles, egg custard and other easily absorbed and digested food, avoid eating spicy, stimulating, fishy, too sweet, too salty food, avoid smoking and drinking alcohol, as well as with the use of antibiotics and other medication. If the symptoms are not relieved, you need to go to the hospital in time to rule out the possibility of peri-tonsillitis or peri-tonsillar abscess. If you cannot eat and are weak, intravenous infusion of glucose and potassium ions can be given if necessary to avoid ionic disorders and weakness of the limbs and delay the healing of the disease.
