Sinus infections occur when there is blockage or inflammation of the nasal passages, says the Mayo Clinic. The most common cause is a cold, but allergies and upper respiratory tract infections also cause sinusitis.

This discharge sometimes causes an odor in the sufferer's nose that even others who are near to the sufferer detect with their own noses. Since these symptoms also accompany the common cold, timing is important. There is reason to suspect a sinus infection is present if symptoms persist longer than 10 days.

Sinusitis frequently clears on its own without treatment, or with medication to ease discomfort, says WebMD. Sinusitis that lingers or recurs may be a chronic infection in need of medical attention, reports Mayo Clinic.
