Hi.
As per your complain it seems that your son is suffering from viral infection and the symptoms of
sore throat,
nasal congestion red eyes can be due to cold.
However seasonal allergies can also show similar symptoms but his symptoms points more towards virus.
The infection will however resolve once the virus will complete its cycle in human body..
As of now he can start with supportive treatment to relieve the symptoms like:
1. Gargle with a warm saline solution that is by mixing 1 teaspoon salt in a glass of water and warm it to make a luke warm solution..
2. Take a combination of decongestant like
Phenylephrine,
mucolytic like Ambroxol and anti allergic levocetrizine and another combination of
Acetaminophen and Ibuprofen..
3. Do steam inhalations..
4. Avoid spicy and chilled foods..
5. Sip on warm water throughout the day..
Hopefully the symptoms will resolve within a week and if it worsen consult a General Physician and get evaluated..
Hope I have answered your query.
Let me know if I can assist you further.
