Mucus mixes with saliva and is swallowed without us being aware of it.

    However, flu, cold, allergy, or sinus infection could cause the mucus to thicken, thus making it harder for it to normally drain. Postnasal drip might start mildly, with no bad smell in the nose or impact on your breathing. But, you should see your doctor if the smell worsens and you begin to wheeze.
