I have had serious sinus issues for many years. I started using this homeopathic nasal spray and it has really worked great for me. It kills the germs / bacteria in your nasal passages and is gentle enough to use everyday. I usually do two pumps in each nostril, blow out any mucus / debris, and spray once more (gently sniff to make sure it reaches deep in the nasal passage). I do this once in the morning and again in the evening before bed. You can check the website for more info:
