My PC referred me to a pulmonologist due to me having a cough for over 10 years when it started to get worse. I come from a family that doesn't believe in going to the doctors, so I had put it off for a while. He had me go for X-rays and did a full blood work up on me. I did have pneumonia associated with COVID after being diagnosed with IPF, which made things much worse (went from 70% use of lungs to about 40%).
I wish you luck. May god bless the two of you.
