What is a Cough?
By Brian Joseph MillerMedically Reviewed by Sanjai Sinha, MD
Coughing is relatively painless, but it can be irritating or distracting to others, and the effort of coughing can leave you feeling achy and fatigued.
A cough, is, ahem, your body's way of responding when something irritates your throat or airways. Coughing, from short throat-clearing to wheezing to full-on hacking, can be voluntary or involuntary, short-term or long-lasting, a symptom of a physical problem or a sign of a psychological disorder.
