@cate123456 Dry can wreak havoc on sinuses (and skin!) Humidification really helps. I've used Xclear spray also, helpful for sinus headaches, and available on Amazon.

Since the topic of sinus headaches came up -- I had a killer of a sinus headache that seemed to be impacting my ear. When my doctor looked in my ear no infection. I would have sworn otherwise. Long story short, I was experiencing TMJ pain, which I attributed to my sinuses. It seems gripping the nebulizer mouth piece between my teeth is not a good idea!
