Help...can't breathe

[ah1979]

I was recenlty told i have asthma and have been taking foradil and intal. I started getting this  tickiling and burning in my chest and throat  about two months ago with tightness in chest and shortness of breath. i have this cold, almost painful burning sensation when i breathe through my nose or mouth. I have a dry cough but i think it is mostly me trying to get ri of the tickle. at first it was just a couple of time a week. now i have had it consistently for about a month.

I was exposed to several toxigenic structural molds about 3 years ago. i was recently exposed again in my workplace to aspergillius and cladosporium. A PFT shows partially reversible small airway obstruction according to my doctor. I received some lab work yesterday that indicates a positive IgG score for Micropolyspora faeni. Everything i read about this says "farmer's lung" or hypersensitivity pneumonitis.

my question is...does a positive result on this protein neccessarily mean thati have HP? do people test positive without developing lung disease? Do the symptoms I am having now relate to HP? Is it reversible? How should I proceed with a pulomologist?...what tests should i ask for?
