Bronchospasm is a narrowing of the airway that usually comes and goes. You may be at risk for bronchospasm if you have a chest cold or allergies. You may also be at risk if you are bothered by air pollution, certain medicines, cold, dry air, smoke, or strong odors. Exercise may worsen your symptoms. Bronchospasms may make it hard for you to breathe.
