Red swelling in a child’s tonsillitis can be treated with antibiotics, and regional treatments can be considered to enhance efficacy, such as pus pocket irrigation or direct drug injection, along with pain relievers to alleviate symptoms. If fever is present, fever-reducing medication can be taken, and in severe cases, medical attention should be sought promptly. If your child frequently experiences this condition, consider surgery after the condition is controlled, and parents should ensure adequate warmth for the child to avoid catching a cold and triggering a recurrence of tonsillitis.
