A nasal wash helps remove mucus from your nose and sinuses. To improve the benefit you are getting from any nasal spray, do a nasal wash first and then use the nasal spray. A prescription antihistamine nasal spray, like Astelin
I had chronic sinus problems for years and took many rounds of antibiotics. Finally I went on an almost all raw food diet with carrot and green juices. This program worked but it still took many years There is a product called Xlear that has grafefruitseed extract in it that is supposed to kill orgaanisms.
P. S. It's me again I forgot to say that whenever I eat anything I create more mucus and I have been tested for allergies and all were negativ. I wasn't tested for food allergies but I have completely cut out all dairy for the last year. I don't know what else to do other than I tried cutting out gluten also without results. Why does eating make more mucus? Any thoughts.
