Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns....
As per your complain the symptoms of
sore throat,
white spots , fever, congestion and
swollen lymph nodes is an indication of viral
throat infection along with secondary bacterial infection..
The white spots seems to be pustules secondary to bacterial infection..
I would suggest you to give him Antibiotics like
Levofloxacin or Augmentin, anti-inflammatory painkiller like Advil, steroid can help in faster reduction in inflammation and ease the symptoms, do warm saline gargles, steam inhalations and decongestants oral as well as nasal sprays to relieve congestion..
Take Vitamin C supplements to improve immunity and suck throat lozenges.
Avoid spicy and chilled foods..
Drink plenty of warm fluids and avoid spicy and hard foods..
Take ample of rest..
In case of no improvement consult an Otolaryngologist and get evaluated..
Hope this information helps..
Thanks and regards.
