Suggest Remedy Shortness Of Breath And Tightness In My Chest

Im not sure if i have a mild form of asthma. I ve noticed i have shortness of breath and tightness in my chest when i exercise or exert myself. I like to go on run s a couple times a week and i m always troubled by the shortness of breath, tightening in the chest and the light headed feeling in which forces me to stop running. I ve also noticed that every year in the fall ever since i was a little girl i ve gotten this really bad cough that causes shortness of breath for no reason and throwing up due to coughing .
