Hi, I've had poor sinuses since my 20's. Exacerbated by wine and some other alcohol. Over the years I found mushrooms, blue cheese, grapes, raisins etc caused the same problems along with tum probs. took me years to work out I was allergic to anything fungal, fermented or yeasty. By then my sinuses in a right old mess causing dreadful headaches. I've taken steroidal nasal spray years now for allergic rhinitis.
As others say, it's vital to drink loads (not coke or fizzy stuff)! You need to keep well hydrated to get everything fluid & flowing well.
I'm not suggesting this is what you have btw, just sayin, there are loads of things that can cause excessive mucus in sinuses giving you post nasal drip which in turn makes you cough a lot which in turn can cause inflammation of the airways.
It might be time to go to the GP and explain you're worried. You may even have asthma or allergic ashma.
Good luck. P
