I had sinus for 5years still going, every night/morning are suffer.
Many doctor, the famous everything same temporary fix only

Last 3years I study oversea, my sinus gone for for 3years
I come back malaysia now
Sinus come back

I think it's food problem. like curry, spice indian/malay one. or malaysian food just cause sinus like the chicken here seem kinda odd and I don't felt nutrition as oversea (For malaysia chicken I eat I feel more cold only IDK, I got no issues like this at oversea)

Any expert in this or fellow victim know what to do?

I have this sinus problem too and I believe it has something to do with the weather or consistency of temperature. This sinus thing will "attack" me whenever there is a change in temperature, for example suddenly walk into a cold aircond room from outside hot environment and vice versa.

Also, morning time when wake up, it happens as well, I have to assume night time while sleeping, weather/temperature is low and when wake up time weather/temperature no longer the same. Weather here is not consistent, between day and night temperature is different. Been to Taiwan last year during their cold season, whole day morning till night also same cold temperature and surprisingly enough I never had this sinus problem during my 2 weeks stay there. Got to love the cold weather there!!!

I have tried quite a number of medication before in the past, including those spray and drop one, unfortunately those only could provide temporary relieve, not a long term one. I think this kind of thing no medication can fully cure one. When it gets worse until cannot tahan, I use "illadin" drop, then at least night time can sleep peacefully!

Inside aircon in malaysia also will get sinus for me.... IDK really maybe air quality
how u got rid of it?

yeah i realize that it get worst when aircon
But it never happen for me when aircon at oversea - no sinus and I slept like baby. Why only in malaysia get this.....

surgery? how much was it in total
