30,000,000 people suffer from sinusitis, making it the most popular (!) disease in the US. I've had it off and on for years.

After much research, I'd like to share three tips:

This book is the single best one on the topic. It's smart and practical.

You might buy a nasal irrigator and use it twice a day. It's super weird, and it costs $100, and it works. Really.

And you could (I know, it's horrible) drink two tablespoons of apple cider vinegar every day.

This post is totally off topic, but if I can help a few of you make it through a long winter, it was worth it.

(Actually, to bring it back on topic, the question is: why didn't you know about this stuff already? The answer is that people don't like to talk about it. They don't like recommending a book about health because what if you don't like it or it backfires? And they certainly don't like talking about nasal irrigation. Who would? At a dinner party? At a golf game? When, exactly, does it come up in conversation? It turns out that word of mouth is a complex beast. Certain ideas spread merely because they're fun to talk about. Others, even if they're good ideas, languish. Not a lot you can do about this, unless you can hook your product or service to an idea that's naturally viral, as opposed to insisting that the market do the right thing.)
