Hi Tony,
I absolutely agree with Charlene that having your scan looked at by a pulmonologist is essential. I’m actually surprised that a technician gave you your report. Usually radiologists read scans. Is it different in Thailand? Also you do need a doctor to make an accurate diagnosis and treatment suggestions. I would suggest to you that deciding on your own to take medication isn’t the way to go. Pirfenid0ne could be the wrong medication for you. Best of luck in getting a diagnosis soon. I know it’s not easy.
