Thank you for your query on Healthcare Magic.
It seems your son is suffering from a viral fever
For fever, you can give Tylenol
in prescribed dose every 6th or 8th hourly depending on the presence of fever.
Give plenty of oral fluids to maintain hydration.Tingling sensation
may be felt during fever.
If there is high grade fever, do tepid sponging with lukewarm water.
If the fever is persisting, consult the pediatrician
for follow up and for investigations.
Hope I have answered your query.
