Such perception of smell may be noticed when there is some sudden change of airflow in nose for instance, when one sneezes, but this goes away when the infection is gone.
Other causes of phantosmia are such as nasal polyps, migraine with aura, dental problems, radiation for cancer treatment in head or neck, smoking, as well as exposure to chemicals. A particular compound that is related to sulfur may be released when there is presence of large number of bacteria in mouth as happens with halitosis. This may cause bad breath with metallic smell.
