Hi Nina, I too, was diagnosed in 2018 and have had very little to no progression over the last four years. I found out I had IPF after a CT scan of my heart showed a secondary finding on my lung and then did a lung biopsy to confirm the diagnosis but other than that the only symptoms I had was shortness of breath, if I was taking the stairs which I really did and clubbing of my fingernails. Whatever you do, don’t listen to what you read on the Internet I spent a couple years waiting to die now I’m spending my time living and if that’s one year or 12 years I’m going to approach each one with gratitude.
