It’s been over a week, but you’re still coughing.
Why?
Unfortunately, the effects of viruses or bacteria can last long after the actual infection is gone. A chronic cough can be the most predicable aftermath of a cold or other viral infection, says Norman H. Edelman, MD, chief medical officer of the American Lung Association.

You Have Asthma or Allergies
Allergies and asthma are common causes of prolonged coughing. A cold can even cause an asthma attack. In fact, some people learn they have asthma after suffering from a cold.
In addition, acid reflux and obstructive sleep apnea can also cause a chronic cough. Notify a doctor if you experience the below acid reflux symptoms:
• Burping
• Heartburn
• Ongoing cough
• Regurgitation
Also, see your doctor if you have symptoms of obstructive sleep apnea, such as:
• Insomnia
• Loud snoring
• Nighttime choking or gasping
