I was diagnosed in September 2022 and am progressing slowing. I use oxygen at night (2L) and when I do anything strenuous. I’m surprised at what is strenuous and what isn’t! I, too, was stymied by “PF” and ILD-PF, and learned a lot from reading this thread. I work out in Pulmonary Therapy twice a week, do an aqua exercise twice a week and do weights. It’s so easy to just sit around. I’m in Denver and the altitude is rough on me, even (or especially?) after four years. I return to home to the Pacific NW or to LA CA two to four times a year and breath much better in those two places.
It is tiring at times to live like this.
