In brief: Sinus inf & smell

Sinus infections can definitely alter your sense of smell.
First of all, with the thickening of the mucous membranes and the presence of extra thick mucous, your smell receptors in the nose don't work as well; and (2) if bacteria are present along with purulent drainage, the germs in this carry their own rather unpleasant odor. Sinus infections can also be a cause of bad breath.
