What is best way to get plem chest clean before secondary infection sets in and antibiotics is needed.

Phelgm: The best way to avoid inspisated mucus in your bronchial tubes which can lead to pneumonia is to keep well hydrated and take an expectorant cough syrup containing guaifenesin. If you have diffuse raising secretions, try postural drainage by hanging your head over the edge of the bed while coughing up the sputum.

Wrong assumption: "Phfem chest" is a viral respiratory situation? Asthma? Chronic lung disease? Typical viral symptoms resolve in time without any med. Can be days to weeks. Specific treatment will be determined by specific situations. Most people need nothing but waste money on useless nostrums peddled by slick scams.
