Running Nose, Flu, Sensiitive, Cough = Sinus?

Recently I found myself not in a "tip top"condition:
- Running nose all the time
- Flu- watery type (not those thick and yellowish)
- Sensitive to dust, air con....
- Light Cough
- Inhale difficulties (especially sleeping in the air-con room)
- My right ears... (seem to be watery too)

and yesterday i was talking to a colleague and she told me her mum went for an OP (due to sinus)...I was afraid that i might undergo OP too....I knew that precaution is better than cure! and i really knew that mine was not those running nose nor flu!Headache~~ Today is P.H. i might consult doc for advice.
I went thru the Net for sinus's symptom. I can't really get what i want!
HOW??
