My father aged 62 is having issue of ILD

My Dear doctors, We are from Lucknow Uttar Pradesh. My father age 62 is having issue of short/low breathing, frequent cough. In other words he can barely breathe. He is getting diagnosed locally by a doctor who advised him now to get admit ASAP. Xray report findings says ILD treatment. We are fine for this and have no issue but just want to understand how much time my father will require to improve and what would be the treatment in brief would be given to him to make him on track. I shouldn't say this but we checked out with one more 34 experience doctor who says he is not gonna ok and things will go like this till he alive. We are quite upset from the outcome of recent visit of doctor. Please find attached X-Ray report for all of your reference. Please it's sincere and humble request to share your valuable feedback and also best treatment place near to our place.
