Hello,
Welcome to HCM,

The history, symptoms and the lab reports suggest me that you may be having flu like symptoms of viral origin. Most of the viral flu are self limiting which will subside by itself with symptomatic treatment.

As your son is getting the fever repeatedly inspite of the lab report coming negative it may be a pyrexia of unknown origin.

Which requires multiple investigation to rule out all possible cause of fever. I would suggest your son to continue with symptomatic treatment for few more days.If the symptoms are not subsiding then you need to undergo investigations.
Thank you.
