I went to my GP yesterday for a follow up on stomach issues (since resolved) and - of course - he said I have yet another sinus infection. I don't even know when I get them any more I guess. Anyhow, he wanted me to try an antibiotic sinus rinse. While it smells and looks like listerine, it is amazing! I used it last night and felt better within an hour. Used it again this morning & feel pretty darned good. Just thought I'd pass this along to those others who have chronic sinus problems.
Maybe it's time to go see an Ear, Nose & Throat specialist instead. And remember chronic sinus problems always have a possibly preventable cause that needs to be investigated. The most common cause is allergies. You may need chronic antihistamine use to prevent them. See an Allergy specialist and get tested to see what it is you are allergic to.
