Garfonzzo, I also have a lung condition, hypersensitivity pneumonitis (HP), which sounds similar to yours. Originally, we are certain it was caused by a goose down pillow that I was sleeping on. The effect of HP is a reduction of the transfer of oxygen from the lungs into the bloodstream. We got rid of the goose down and a course of prednisone and I was better. About 18 months ago, it started to come back. Diagnosed with CML and started Sprycel 100 on Jan 7th 2017. After about three weeks of Sprycel my coughing stopped and I can feel that my lungs are better. Apparently, the CML caused a reaction similar to goose down in my lungs. Getting diagnosed w CML has been one of the best things to happen to me lately! Thank goodness for smart scientists like Dr. Drucker and thank you to everyone that has health insurance that is helping pay for my meds!
btw: I don't fully understand the numbers but initially my PCR was 77.9 after only 30 days it is 28.5. Next appt is at 90 days.
