Same. Dust mite allergies, sinus infections all the time, etc. Wound up having surgery.

3 things helped me:

1. Run filters like these in your rooms (they get discounted a lot, and refurbished similar units are fine) https://www.costco.com/winix-c555-air-cleaner-with-plasmawave-technology.product.100280312.html
2. Clean the room, laundry, etc. constantly
3. Neilmed bottles are a godsend. They work instantly but take a while to get used to, and using these daily was better for my quality-of-life than surgery, medications, etc. I can't stress enough how much of a difference these made in my sinus health.

I hope this helps - good luck!
