Never used it but have heard of it. Seems to work well for the people that use it. And maybe steam but I’m sure you know that one aha
And believe it or not, I’ve actually read that dairy can be related and lots of people that have cut out dairy products have had their sinus problems get way better or even completely go away even some with chronic issues or stuff medicine didn’t help. Might be worth a shot.
Of course, dairy can be hard to quit.
But I’ve had some off and on sinus stuff and I know whenever I eat dairy, I wake up super stuffy/clogged up and stuff the next morning ahah
But I love it too much to ever stick with cutting it out even if it’d make me better.
