I am looking for information/advice for my dad who was has had PMR and GCA for about a year. In he last 6 months, he started having a very hard time breathing and they recently diagnosed him with Pulmonary Fibrosis. This is a man who was never sick a day in his life and boom-- one day he's down and out and hasn't gotten back up since. He's been yoyo-ing on the prednisone from 60 down to 15 and then back up to 60 and is now at 30. When he got so low he experienced blindness and the doc jumped him back up.
I'm wondering here if others have experienced pulmonary comorbidities like pulmonary fibrosis as a result of the PMS/GCA and what have you done to improve the situation.
Thanks in advance.
