If you do not have a cold but suddenly have coughing symptoms, you need to consider some causes. It is more common to have coughing caused by allergic reactions in the airways due to the inhalation of sensitive substances such as cold air, pollen, oil smoke, hydrochloric acid, acetic acid, etc. It is common to have acute attacks of cough variant asthma. In addition, it is also seen as a result of choking due to the inhalation of foreign bodies, such as small toys and peanuts. In addition, it can also be caused by traumatic rupture of the pleural cavity, resulting in a tension pneumothorax, an initial obstruction of airflow in the lungs, a decrease in lung function and sudden onset of coughing symptoms.
