Sinus Mucous Tenacious Strands

Since last year around 6/2009 I have been troubled with mucous that is long and thick almost choking at times... It is most troublesom in my home Bay area Ca. Luxury apartment.
NOTE: In one apartment there where these black fibers that came from the vents, I covered the vent with a T shirt it too is now permantly stained with this black end image of the vent intake grid, "washing does not remove"In this 30 day period after this tenacious form of mucous took over, my doctors tested and the ENT said there was nothing he could give me to reduce the flow of mucous (?)what(?) I spend 1 -2 -3 hours a day in the lavatory hacking and releasing mucous from my throat and sinus passage. also normal flora grains where found... something is missed. I also get a methane like breath taking odor in my sinus passage if i begin to press or scrap a strange rash on both heals of my feet.. I have received little intrest from the facily known as K****r please help something is wrong.... I will travel...
