Some great ideas here, and a few more I can add via my experience, being a chronic sufferer of sinus disease most of my life. I know this thread was started for general sinus drip and inflammation. But since the discussion is about sinuses, I'd like to contribute. After seeing countless doctors and trying 1000's of products, IMHO probiotics are the answer. But there is still so much we (as in research) don't know. BTW, I tried L. Sakei probiotic and it did not work for me, proving not everything works for everyone. I can go on and on about sinus treatments, but here are my most current and promising ones:
One particular probiotic I found effective for sinus infections, is DE111. DE111 is a trade name for Bacillus Subtilis. I'm using this product, although there are others on the market with same strain:

Here is the article that inspired me to test this product for chronic MRSA, staph being a common bacteria found (and likely the cause) of many chronic sinus infections:

What I discovered is, RE111 works as good or better than Rx antibiotics or smart silver, without the long term negative consequences. And the potential added benefit of re-establishing a healthy sinus biome. Like other topical sinus treatments, this probiotic also requires 2-3 times application per day to be effective.
As I do when testing other probiotic caps, I break open and mix the powder with sterile water to create a paste, then apply into sinus cavities with long Q-tips. I find these helpful to get deep into sinuses:

For occasional use in treating sinus issues, you also can't beat the new generation of smart silver. The smart silver made by Bio Nativus is equally as good as the one originally made by Desbio, but much cheaper and easier to get. Buy the 30ppm version and use a sinus spray applicator.
Another psuedo probiotic which has long term promise, I'm also testing both for my sinus and gut:
https://humanlongevityfilm.com/product/restore-for-gut-brain-health/ The doctor who is marketing this product has some relevant points about why it works, although claims it will take 6-9 months before change can be observed. Dr Zach Bush has a few Youtube vids to learn more. To me it's worth the risk of investment with users already posing positive feedback here:

This product is also sold in sinus spray bottles.
Lastly, if there are gut issues like SIBO, all bets are off to resolving sinus issues, regardless of what you do. Fix the gut first. And it's worth noting, unresolved sinus infection can develop into a gut infection from the infected sinus drainage. This sets up a cyclic loop of worsening sinus and gut conditions. Typical symptoms are loose stools, bloating, gas, and stomach discomfort. I have gone in circles trying to resolve sinus issues, only to find out my gut was sabotaging all efforts. Unfortunately, most of the commercial soutions for SIBO are ineffective. I have tried many of these often expensive herbal preparations for SIBO, which claim it take months to get full results. That is simply hogwash. There are Chinese medicine preparations that work far more effectively, and often clear infections in a matter of days. The point is, resolving gut issues can oftentimes clear up stubborn sinus problems. It's a 2 way street.
