An 8-year-old boy initially experienced pain when swallowing and noticed a hoarse voice. Now, he has a persistent high fever. How should it be treated? Treatment should first include symptomatic anti-inflammatory medication based on the child’s symptoms. Concurrently, regional treatment can be chosen to enhance efficacy, methods include tonsil crypt irrigation, direct tonsil injection, etc. Painkillers can also be administered for throat pain. If the child still has a fever, consider antipyretic measures. If the temperature exceeds 40 degrees Celsius, it is necessary to seek medical attention promptly. If your child frequently experiences this condition, consider surgical treatment after the illness is controlled, to avoid recurrence. During this period, ensure the child gets adequate rest and consumes more vegetables and fruits.
