Hi I did a Half Marathon last Sunday. Since then I have been experiencing shortness of breath during most of my activities ie stair climbing, boot camp even yoga.No history of asthma. This has never happened to me before.
I would be inclined to see a doctor and have it checked in this case. I don't know why it would happen this quickly, or if it's a result of running the race. But it can't be considered normal and it should be evaluated.
