question: My son, 9 yr old,  has had a spiking fever for the last 48 hours. He has no other symptoms when we get the fever down but when it spikes up to 103-104 he gets a cough... what could that be? Should I take him to the doctor, I mean I have no symptoms but a spiking fever. It takes 1 advil and one tylenol to get it to come down every time.
