Yes, I suffer from indoor allergens. My sinuses have been dripping like a faucet. Dr said no infection can be seen on cxr or CT and my lungs sound clear. He said he didn't want to take any chances and put me in the 6-day prednisone treatment.
And as far as him thinking I've had it many years is because I have been exposed to every single risk factor. I grew up with nothing but wood stoves for heat and xtreme amounts of second hand smoke, suffered near death pneumonia at 16, worked in both wood and paper factories, worked in a motor pool in the military surrounded by diesel fumes, and I smoked...he doesn't believe I have Alpha 1, just wants to rule it out. He said COPD takes years to developers unless there is high exposure to risk factors (hence, young diagnosis). I smoke 1 pack a day for probably 10 of the 20 years I smoked. Rest of time was only half pack or less. Plus I had quit several times in between.
