Hello,
It is very likely this is a flu or other common viral infection that will take a week and will go away.
Strep throat generally does not cause stuffy nose and
cough, these go more with a viral infection.
If there is no
fever longer then 3-4 days there is nothing to worry.
Sometimes a viral infection may get complicated with strep throat but this would mean that instead of him improving in the next 3-4 days he gets worse and the throat gets worse and in this case, he needs to see his doctor.
If fever lasts more then 3-4 days is another reason to see the doctor, it might still be a viral infection but it is better to make sure.
Meanwhile, he can take
paracetamol and
ibuprofen to help with aches and pains and drink plenty of fluid, try to eat a frequent small amount of food to help with the appetite and rest well.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Antoneta Zotaj, General & Family Physician
