I am a 15 year old girl and I love plying sports and stuff. I used to love to run when I was younger, but then I started to not like it anymore. I had trouble breathing . It wasn t till year later I told my parents about it. I went to a walk in and they prescribed me a inhaler . I had to take it Be there in 15 mins before I exercised. It wasn t helping so we went to a specialist and they said I have symptoms but there was nothing there too show that I had asthma . I kinda just left it alone and now I am wondering am I just maybe out of shape. As I got older I got different symptoms. I don t wheeze but breath heavy and my chest tightens and hurts and I get mucus in my throat making be gag when I try and breeze. I am just wondering if maybe I am just really out of shape, but that seems weird cause I am not a lazy person I love to be active, but maybe someone could help me out
