Sorry you didn't get more responses. This may sound strange, but my experience is with horses. A lot if our cutting edge treatments in humans come out of the race/show horse world, like the best lung, joint, digestive supplements/treatments available. When horses are in stabled environment, they are exposed to massive amounts of dust, and depending on their geographic location, this dust can contain fungus spores that can reek havoc, like in the desert of the American southwest, coccidioidomycosis, or cocci is caused by the soil-dwelling fungus, Coccidioides immitis, aka Valley Fever. You need to find the "why" inside your lungs to get the best treatment. You need to see a pulmonary specialist who will do biopsies, AND when a lung biopsy is considered, a surgical thoracoscopic biopsy should be obtained, as transbronchial lung biopsies are generally inadequate for diagnosis. Also, since your condition was acquired as the result of military service, you should apply for military VA disability payments, be sure to include all medical paperwork from the military and civilian (you must request copies). Make sure everything is filled out completely, send certified mail, KEEP COPIES of EVERYTHING! The VA can help you with this, you give them a limited power of attorney. NOTE: They will mishandle your request ( entire process should only take six months), so after the six months of runaround, write your eldest, most influential state senator. You will include copies of all VA correspondence, and medical records in the package. Here is the KEY! In the letter, at the end, request that your senator investigate the mishandling of your VA disability claim!! This will force them to process the claim, or go before a Congressional investigative committee! I have helped many other veterans, and wish you the very best!
