I have been experiencing a foul odor when I inhale or exhale in my nose. I swallow and I have a funky taste in the back of my throat. When I bend down my nose drains and it is a yellow colored drainage with an awful odor. I don't have a sinus infection or bad teeth/gum, I don't know what this is but it is gross!

How do you know you don't have a sinus infection? That's exactly what yellow smelly drainage indicates...
