Yesterday evening, took my daughter from kindergarten with fever, today we have cough and phlegm + temperature 38 all day, temperature before bedtime 39.4, voice by evening hoarse, daughter fell asleep sitting on the sofa (for the first time). Something scares me, I never had such weakness before, to fall asleep sitting down, apparently due to high temperature, before that gave Panadol, hoping it will help bring down the temperature. Tomorrow we'll definitely call a doctor, can you tell if this is laryngitis? We've never been sick with a hoarseness before. On Sunday, she ate ice cream outside, could it manifest symptoms after two days for this reason?
