Asthma is quite common in clinical settings. Asthma attacks often occur suddenly when exposed to allergens, during physical activity, emotional excitement, or infections, presenting symptoms such as paroxysmal coughing, chest tightness, wheezing, and breathing difficulties. Breathing difficulties often manifest as expiratory difficulties. Symptoms of asthma typically alleviate upon leaving the allergenic environment or after the application of bronchodilators. These are the typical clinical presentations of asthma.
