what does shortness of breath mean for my asthma

Asthma is characterized by inflammation of the bronchial tubes with increased production of sticky secretions inside the tubes. People with asthma experience symptoms when the airways tighten, inflame, or fill with mucus.

Common asthma symptoms include:

Coughing, especially at night
Wheezing
Shortness of breath
Chest tightness, pain, or pressure
Still, not every person with asthma has the same symptoms in the same way. You may not have all of these symptoms, or you may have different symptoms at different times. Your asthma symptoms may also vary from one asthma attack to the next, being mild during one and severe during another.

Some people with asthma may go for extended periods without having any symptoms, interrupted by periodic worsening of their symptoms called asthma attacks. Others might have asthma symptoms every day. In addition, some people may only have asthma during exercise, or asthma with viral infections like colds.
