Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that your son is suffering from upper
respiratory tract infection, also known as
Common Cold and the symptoms of lingering cold and cough along with headache are due to it only.
At times sinus involvement or infection can occur secondary to cold and can lead to Headache..
As it is a viral infection it will not resolve with antibiotics as the antibiotics acts against bacteria and not viruses..
The infection will however resolve once the virus will complete its cycle in human body..
As of now you 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 this information helps..
Thanks and regards.
