The duration of your cough will determine its acuity. A cough lasting less than 3 weeks is acute, coughs lasting 3 weeks to 2 months will be considered sub acute, and cough lasting more than three months will be determined chronic. Cough is naturally a reflex of the human body to prevent fluid from going into your lungs. Depending on your cough acuity there maybe different cardiopulmonary disorders that can exacerbate this. Schedule an appointment to evaluate it.
