Hello and hope you are doing well.
Cough, chest tightness and breathlessness the three symptoms are the triad of symptoms for Asthma. It is a disease affecting the lungs causing narrowing of the airways, usually due to an allergic reaction to triggering factors. Therapy is with bronchodilators which cause the airways to dilate. You will need to consult your doctor who will do an initial clinical assessment. He may even ask for blood test and an X ray. Lung function tests could further help in evaluation.
Hope this helped and do keep us posted.
