what is chest congestion
Chest congestion is a common symptom of respiratory tract infections (like the common cold). Chest congestion is what happens when the mucus membranes (mucosa) that line your airways jump into overdrive.Mucosa cells are attacked and become irritated and inflamed because of some irritant youâve breathed in (like dust, bacteria or a virus). Extra mucus (thatâs thicker, too) is produced to flush out the intruder.hen you have chest congestion, you want to thin and loosen the mucus thatâs caught in your lungs so itâs easier to cough out. To do this, youâll want an expectorant like guaifenesin. Use as directed.
