As a kid I had really bad asthma. I was constantly sick and in the hospital. Around 17 I no longer had issues with my asthma. It was if it disappeared. Now that I am 22 it has come back with a vengeance. I have been running a lot lately. At my 5k on Saturday I did not realize so many smokers would be present and my asthma kicked in. I couldn't run past 1.88 miles and had finish in a walk. I did not realize at that time that I was having an asthma attack. Eventually, I headed home and that is when the wind was literally knocked out of me. I couldn't catch my breath and kept coughing. I used a rescue twice that night and once this morning.
