Our son is almost nine, it Is Monday 2:30 in the am, he has had a fever off and on since Friday early morning, his energy level has been pretty active most of the time, he is coughing occasionally with a runny nose. I have three under the tongue thermometers and they are all weird numbers under 98 degrees, so definitely inaccurate. Four years ago at this time he had similiar symptoms and he had pnemonia after pediatrician sent him to hospital for chest xrays, We will be taking him to the pediatrician later today.
