My post bd test showed small airway obstruction. my dr rx advair & treat it asthma. only symptom is 6-month-long chronic dry cough. could this be related to lung nodules previously found on ct instead of asthma?

Mgt.: It would be helpful to know the actual percent predicted values on the PFTs report, but from your description you did improve with the bronchodilator. Your physician has prescribed a long acting bronchodilator and anti inflammatory agent. The CT finding of nodules, may be related to a number of conditions, but it would be less usual for asthma. A chest radiograph and follow up may be indicated.
