Lucy is a 6-year-old female who was brought to the clinic for worsening shortness of breath and chest tightness which caused her parents to keep her home from school today. Her mother reports Lucy has had a cough for “weeks” without a fever, which was attributed to seasonal allergies. Lucy first reported feeling short of breath yesterday after school, at which time she was also noted to have a cough. Her mom could hear her wheezing.
