That is not normal. Not to sound alarmist, but please see your doctor. Chances are it is exercise-induced asthma, but it's important to rule out other things. And if it is EIA, a couple of puffs on a prescription albuterol inhaler before a run will help a lot. You may also need a daily preventative, such as Advair, if your condition is serious enough.

Running is hard for me too, my HR gets high, and I huff and puff, but it should NOT hurt or ache like that!
