What symptoms accompany a lingering cough?

So you’ve had a cold, and you’re starting to feel better – your throat isn’t sore anymore, your nose has stopped dripping – but that pesky dry cough just keeps lingering. This lingering cough can really get in the way of your day, interrupting those important work meetings or keeping you from getting back into your gym routine, not to mention getting in the way of a good night’s sleep – leaving you feeling tired and lacking your usual oomph. 

Coughing is a natural response to help protect your airways. This uncontrollable – involuntary – cough reflex is triggered when nerves in your airways are stimulated. And so many things can set off these nerves! As well as infections and allergies, things in the air such as smoke or dust plus normal body fluids such as mucus can all irritate these nerves and make you cough.

These triggers often cause what’s called an ‘acute’ cough, which usually gets better on its own within a few weeks. But sometimes, at the end of a common cold, a dry cough can stick around or ‘linger’ for a little longer. As well as triggers, a lingering cough after a common cold also involves what’s called upper airway hypersensitivity. Basically, this means that your cough nerves have become over sensitive to the slightest of triggers, and are over firing cough messages to the brain, giving you this maddening and continuing urge to cough.

What are possible causes for a lingering cough?

The most common cause of a lingering cough is a viral infection of the respiratory tract, such as the common cold. Coughs that accompany the common cold often linger long after the other acute symptoms of the infection have eased.

  • Fever
  • Coughing up blood or lots of mucus
