question: Hello, I am a 24 yr old male in relatively decent shape with asthma. I just ran two miles in 14min 18sec and the center of my chest felt crushed and I had a bloody taste in my throat. I just started back running last week after about 6 months off (ran two miles three days last week at a 19min pace) and I am 6 190lbs. Is this anything to worry about?
