Thanks for posting your query.
With the available described symptoms, you are most likely suffering from acute viral upper respiratory tract
infection with sinus
involvement and possibility of secondary bacterial infection.
Presence of sore throat
, cough with sinus pain suggests the diagnosis.
Sinus are empty space in scalp
bones and predisposes for infections.
You should consult with internal medicine specialist and should go for thorough check up.
You should take complete antibiotic course (to prevent secondary bacterial infection), combination of decongestants and anti allergic, mucolytics and anti-inflammatory.
Avoid cold drinks, oily foods, yogurt.
Perform gargles three times in day; a glass of lukewarm water along with a pinch of salt.
You should take proper bed rest
