Asthma
Not every person with asthma has all the signs and symptoms of asthma all the time. A person may have some signs and symptoms during one asthma attack and have different symptoms during another asthma attack. Some people with asthma may have long periods of time between asthma attacks where they show no signs and experience no symptoms of asthma, while others may have some or all of the signs and symptoms everyday which become more severe during an attack. It also depends on what type of asthma a person has and whether they have a mild, moderate or severe case.
