Had Cold And Felt Presence Of A Bad Odor From The Nose. Looking For Cure
The presence of a bad odour from the nose, in a person with a history of a cold suggests that the sinuses which are connected to the nasal passages may have a bacterial infection.This is in addition to the viral upper respiratory infection that you would have started off with.
Most upper respiratory tract infections (cold) are viral but in this case there may be bacterial superinfection (when one infection occurs when another is going on)
In some persons, a malodour from the nasal passages may indicate a fungal infection but this is not at likely as a bacterial infection..
You may want to visit your doctor for an assessment.
Normally the course of treatment would involve the use of oral and topical decongestants and mucolytic medication to decrease the mucus and increase its drainage.
An antihistamine would also be helpful.
You doctor may suggest adding an antibiotic to that regimen.
I hope this helps, feel free to ask any other questions
