I can't run, no matter what I do!

I see that someone else has already suggested asthma. I was diagnosed with exercise induced asthma as a teen and what this basically means is that if I know that I am going to be running to saying going to a Zumba class that I need an inhaler. My son also suffers from this. I suggest that you go to your doctor about this, don't keep trying to run without seeing your doctor. It can be dangereous.
