im 16 years old , and im some what active , i dont smoke or drink nothing like that , but i have a hard time breathing sometimes and it hurts to breathe sometimes to , when i run for about 45 mins , it hurts like some one is sitting on my chest and i feel dizzy after that ..
sometimes it will be random when i have a bad time trying to breathe like today , its not all the time only when i walk really fast , jog or run ..?
my parents said its not athsma , so i dont know what it is
