I have the similar chronic sinus problems. Dust seems to be the biggest culpret with me, so I've encased my bedding (especially my pillow) with the dust mite protective covers and use the mite stuff when I launder my bed linens. I also have cats that I am sure aggrivate it, though I haven't been allergy tested. I take one benadryl capsule every night and one Sudafed 12-hour every morning. If I miss a dose, I definitely will get an "attack." I also use saline mist every morning in my shower. This remedy seems to relieve the pain the most when I have an attack. Good luck. Stay in touch.
