I've read the other posts, but this isn't a recurring thing, I don't smoke, I'm not on any meds, I'm not overweight, I exercise... I got the flu - bad for one day (achy all over, headache on my temples), the next day the achiness was gone but I stayed in bed. Today, the third day, I feel much better, but am left with a slight cold and am taking it easy. I do cough, but only once in a while, and when I do, it sounds like I'm not getting enough air. When I blow my nose, it smells really bad, and I can taste it every once in a while in the back of my throat. Any ideas of what the cause may be and what I can do? I think when the cold passes, the smell will be gone, but I never had this before with a cold. Thanks.
