Use to be sinus sufferer too. I even tried dripping apple cider in my nostril. Hurt like a mother. My triggers are milk and sugar. I didn't stop consuming them, I just cut down. Miraculously, my sinus disappeared on 1st Jan 2018 until now. I'm thinking to write a blog about it too...when I'm not so lazy lah. Thanks for sharing so much info and tips! Upvoted and followed you.
