I am just recovering from a head cold. It started approx last Tuesday / Wednesday. My symptoms were a very runny nose (clear and watery), no chest congestion, repeated sneezing the first few days ( hard sneezes), no fever. I had mild chills down my back, most of which I associate with fighting a cold. I haven't had a cold for several years and did not take any cold medication. Most all symptoms have subsided. I can now breathe through my nose, however today I noticed an unpleasant odor coming from the sinus area. I don't ever recall having this foul smell before. I've tried blowing my nose, but without much resulting content.
