Bronchitis

Bronchitis is when the tubes that carry air to your lungs, called the bronchial tubes, get inflamed and swollen. You end up with a nagging cough and mucus. 

Symptoms of both acute and chronic bronchitis include breathing problems, such as:

• Chest congestion, when your chest feels full or clogged
• A cough that may bring up mucus that’s clear, white, yellow, or green
• Shortness of breath
• Wheezing or a whistling sound when you breathe
