I don't even know what I have. I've had nodules appear and disappear on my CAT scans. I had a lung biopsy (VAT procedure), I just had a bronchoscopy in 11/08. I've had 2 bouts with pneumonia, a pulmonary embolism, dry cough every day, shortness of breath on exertion, a positive TB skin test. So far they say I have MAI bacteria in my lungs and COPD (mild emphysema). I wonder if these symptoms point to sacoidosis. Noone has mentioned it as a possibility but lately I have come to mistrust my doctors because they seem baffled by my case.
