I've been getting chronic sinusitis with frequent sinus infections for quite some time now. I've gone to an ENT and got CT Scans of the sinus and brain. At one point my ethmoid sinus was a bit inflamed, but other than that nothing to note. I've been receiving allergy shots for about 2 years now. I'm using nasacort aq and zyrtec for allergies, but still suffer from sinusitis. I've made an appointment with a different ENT and will ask for an MRI this time to see if I happen to have a polyp or something that can't be seen on a ct scan. Have any of you had a situation like this and found relief from a home brew concoction or otc product? I've read about quericiten...I was gonna stop by VS and pick up a bottle. I'd love to hear any suggestions. I also use a neti pot to help clear sinus'. I never have runny nose, sneezing, etc,,, just pressure .
