Flu/Cold symptoms Air Smells Really Bad?

Honey , I'm pretty sure you have a sinus infection. If the air smells like an infected wound wrapped in a dirty sweat sock, that would be it. The very sore throat is from post-nasal drip. Here's an easy test. Bend from the waist as far towards you're knees as possible. Stand up very suddenly, If your face or behind your eyes pounds really badly , that would be sinus pain, not a cold.
