One thing to consider with Sinus problems is if they are releated to your drinking habits. My dh looked into sinus problems, which I suffered terribly from, and found it was directly related to liver health. I started to pay attention to the timing and sure enough I was getting my sinus trouble in the few days after or even during a night of drinking. I now don't drink, and haven't had any sinus problems at all. I'm not saying you all need to give up alcohol but just be aware of the connection.
Cheers,
