I've read over this forum, and I wanted to add something that has helped me. For the past three years, I too had a bad smell coming from my nose and constant throat clearing. I've been to many doctors, had a ct scan and mri, but my sinuses are clear. It turns out the problem was really my stomach, perhaps too much acid. Prilosec and Calcium Carbonate have helped immensely. Hope this helps someone....
