Exercise Induced Asthma?

I posted a thread on Slowtwitch over the weekend. I posted that I thought I had exercise induced asthma and based upon what others said, I probably do have it. When it's happening, I get a tightness in my chest when I take a really deep breath. It hurts right where my trachea and bronchi are located. Afterwards, that same area is sore for a couple of days when I take a deep breath and I describe it as "sore lungs". Also, sometimes after I race really hard, I'll get these monster coughing fits that last for minutes. I don't think I have a bad case of it, but I think it's enough to concern me when I get this "sore lungs" feeling.
