You should visit your doctor if you experience any shortness of breath that is not expected from an activity and the current state of your fitness or health. Breathing difficulty that comes on suddenly, is persistent or interferes with your daily activities should be evaluated by a medical professional.
Shortness of breath that does not decrease with treatment or that is accompanied by other symptoms like chest pain needs urgent evaluation possibly in an emergency room type setting.
