question: I have shortness of breath after 1/2 of running with lower back pain. The LBP is sharp burning feeling and I can t continue after the sharp pain has disappeared. My throat gets dried up fast with the first two minutes running and feels like throat is clogged. I have no history of asthma. I am 15 lbs over weight but still exercise on a regular basis but just can t exercise long enough due to LBP. I have no history of injuring my back.
