I was diagnosed with asthma following a severe case of pneumonia in 2006, but I wonder if that diagnosis is accurate.  I have shortness of breath; coughing all throughout the day and sometimes at night; sputum that ranges from clear to yellow; wheezing (mild to moderate); and, difficulty with general exertion.  I have no allergies and have no asthma attacks.   Most articles I have read reference allergies and asthma attacks

while my symptoms are daily (for the past year).  I have tried Advair and Albuterol inhalers, but I didn't have any relief.  I also tried a nebulizer with atrovent and xopenex, which was not that helpful.  I just started pulmonary rehab and I am hoping it will help give me more strength and endurance.  Please let me know if I am describing asthma.  Thanks!
