This image depicts the difference between a healthy lung air passage and an unhealthy lung air passage.
Swelling of airways in the lungs produce mucus in the lungs and makes you cough.

Symptoms of acute bronchitis last less than 3 weeks and can include:

  • Coughing with or without mucus
  • Feeling tired
  • Congestion
  • Sore throat
  • Mild body aches

A virus usually causes a chest cold. Bacteria can sometimes cause a chest coldbut even in these casesantibiotics are NOT recommended and will not help you feel better.
