Prior to last month, I had occasional, mild, exercise asthma and one asthma attack 5 years ago related to altitude sickness. 
Last month, I picked up a virus. Chest to bronchitis to bronchial asthma.  I ended up in Emerg where an IV steroid push, 24 Ventolin and 18 atrovent puffs improved me by 10%.  I was given magnesium by IV which derailed the attack. I was sent home on steroids and an antibiotic and told that I would be seen by the pulmonary clinic because they think I have COPD. History of smoking and I am a woodworker.  
Four days ago, there were rebound symptoms after steroid d/c. (I am on hydrocortisone 25 mg/day and that's another story).  I ended up in Emerg again and sent home on a two week steroid taper.  I am feeling better but don't know if I am improving, or if prednisone is masking symptoms.  Coughing less, painful ribcage, SOB with all activity.
I will be having some sort of pulmonary assessment and would like to be an informed participant.  Any insights or advice welcomed. 
Is it a big deal that 50 inhalers in a day did not resolve the bronchospasm?  Is needing magnesium IV some kind of warning? The Drs are interacting with me differently. One said to come back if I have problems and that they would rather an unnecessary visit than having to intubate me.  All this seems rather foreboding for a guy who hasn't even been diagnosed yet.
