Infectious mononucleosis
Infectious mononucleosis #3/allergic agents (bacteria/molds/fungi), paints and other chemicals, lead….and the list goes on, to include your visible fiberglass. One could conclude from this that many, if not all your symptoms are in response to your sustained, basement exposures. As it might be difficult, if not impossible to isolate the cause(s), the best suggestion I can provide is that you should relocate your office and completely avoid the basement.
In general, fiberglass alone has not been implicated as a cause of serious lung disease. But, there is a wide range of fiber size and some, because of their size, are much more respirable than others. The good news is that the evidence uniformly supports the belief that fiberglass is not a carcinogen.. In short, cigarettes and asbestos for example are true carcinogens. Given the state of your basement, however, you may well have been exposed to other toxins or carcinogens.
The first thing you should do is to totally absent yourself from the basement and then keep a diary regarding the frequency and severity of your upper and lower respiratory symptoms. It is conceivable that you might experience a significant decrease in your symptoms. You should, however, have baseline pulmonary function tests and a chest X-ray performed. The doctor you see should not be just any doctor or, for that matter, just any pulmonologist (lung specialist). You should seek out a physician trained in both pulmonary disease and occupational/environmental medicine.
You could check with your local Medical Society regarding finding a physician whose training meets these specifications. One such clinic is at National Jewish Health in Denver, Colorado; an institution that specializes in allergy, immunology, environmental medicine and a variety of pulmonary diseases including but not limited to asthma, COPD, allergic/immunologic lung disease, occupational/environmental lung disease, rheumatologic lung disease and lung diseases of uncertain cause, such as Sarcoid and Pulmonary Fibrosis.
Good luck
