I am only able to run for maybe 6 meters and then i am wiped. I can't breath, my legs are already throbbing, i have chest pain and stomach pains. I am in JROTC and Physical Trainging is a HUGE part. But i know it's not asthma because i was put on an inhaler and the ONLY affect was i got shakey. There was no change whatso ever to the postitive. So what could possibly be wrong with me? I really need to be able to run, or else i may get kicked out of JROTC which is basically my life. Please help.
