Good day everyone, for those whose children have had tonsillitis, what can be done to ease their condition? And what did they eat? Yesterday she ate very poorly, and at night her temperature was 37-38-39, in the morning she was hoarse and complained of pain in her throat and headache. How did you treat it, what else can help so that it gets better? The doctor prescribed a spray and another syrup for coughing, although she doesn't cough much yet. She cries more because she is in pain. ?
