Asthma is the disease in which airways of the lungs are always inflamed. Airways, also called bronchial tubes, allow the inflow and outflow of air from the lungs. When swollen, the air flow is restricted and thus the patient experiences difficulty in breathing. It is a chronic disease and aggravates during and after physical activity causing shortness of breath and chest pain.
Primary Symptoms include:
