what makes mucus form in sinuses
Phlegm is a mucus-like substance produced by the lower airways, such as the lungs and the respiratory system leading to the lungs, not by the nose and sinuses, which produce the mucus that streams out of or clogs up your nose. You may not notice phlegm unless you cough it up as a symptom of bronchitis or pneumonia.ere are some of the mucus problems Ellis sees and his recommended treatments: 1  Post-nasal drip (thick mucus). 2  Take an expectorant (this thins mucus and phlegm), drink lots of fluids, breathe through a warm washcloth, and use steam to make the mucus more liquid. 3  Congestion (blocked nose).
