These symptoms may indicate a problem with the lungs:

• Chronic cough (eight weeks or longer for adults and four weeks or longer in children)
• Shortness of breath
• Difficulty breathing
• Increased mucus production
• Pain or tightness in the chest when breathing

These symptoms can be the result of injury or disease to the lungs or a problem at any part of the respiratory system. If these symptoms persist, it’s important to see a lung specialist to determine what’s causing them, prevent further damage and provide relief.
