A cough can be due to an upper or lower respiratory infection. Upper respiratory infections indicate an infection or the nose, para-nasal sinuses, middle ear, pharynx, tonsils or larynx. Lower respiratory infections indicate infection of the trachea, bronchi or the lungs’ parenchyma. Upper respiratory infections are more common and easier to acquire than a lower respiratory infection . You can request an X-ray image of the chest to exclude lung infection (pneumonia).
However, a cough is not always caused by infection. Coughs are also due to an allergy or some kind of irritation (gases, dust etc.). You can consult an ENT-specialist and a pulmonologist about your condition for more information and to follow up.
