Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems like Upper Respiratory Track Infection commonly known as Common Cold and is Viral infection..
Cold has led to
sinus headache infection causing Sinusitis..
I would suggest you to start taking a course of antibiotics like Azithromycin or
Levofloxacin to prevent or treat secondary bacterial infection..
Take Advil to reduce inflammation and pain..
Decongestant nasal spray, saline
nasal irrigation, steam inhalation and use a humidifier in your room..
Take Oral decongestant like
Phenylephrine and mucolytics like Ambroxol..
Avoid spicy and chilled foods and maintain a good
Oral hygiene..
Drink plenty of warm fluids and take ample of rest..
Hope this information helps..
Thanks and regards.
