PFT shows Mild Lung Obstruction Inhalers not working

[ducksfan]

A few months ago I started having problems with my breathing, more specifically not being able to get full breathing response.  So I had a chest x-ray done which came back normal, then a CT scan of my lungs which came back normal and with no clotting.  I had a PFT done by my pulmonologist and it came back with a 69 reading for the one that showed Mild Lung Obstruction (FEV1/FVC I believe).  After inhaler was administered during the test it only increased by like a few % to 72 I think.  Thus asthma was diagnosed and I've been using albuterol, foradil and asmanex and was recently also given Advair, none of these seem to be helping at all with my breathing however.  I still find myself struggling to obtain full breaths.  The condition actually seems to improve when lying down for some reason and if/when I can get my full total breath while lying down, the right side of my chest/lung/throat not sure which makes a cracking type of sound.  I have some mild wheezing on exhale normally.  This is all at rest.  

The right side of my chest (on the pectural muscle) has recently become painful when pressure is applied there which I think is from the constant struggle with the breathing creating more work there.  I have noticed some more clearer vein markings from that location up to my underarm.  Some other strange things I have noticed are increase in vein markings on the tops of my feet.  Could this all be more vascular in nature rather than a lung condition?

The reduced FEV1/FVC ratio does suggest mild obstruction.  That, combined with audible wheezing strongly suggests asthma.  However it must be determined that the wheezing is not coming from the upper airway.  Conditions other than asthma can cause wheezing and obstruction and you might ask your doctor about the possibility of these.

The relief of shortness of breath when lying down following an upright position has been described in persons with blood vessel disorders of the lungs, called shunts, but these are almost always evident on CT scans.  The normal CT scan is strong evidence against recurrent clots to the lung but not 100% sensitive.

You may have to have a bronchoscopy to rule-out other forms of airway obstruction.

Also all blood tests have come back normal.
