Thanks for question. I AM addicted to Prednisone due to low dose daily usage for 35 years or more. So that is now causing the muscle atrophy that RA also does. It’s frightening as I I don’t know ‘what or when’ things will go. Lost 4 glute muscles last Dec. Seo walking is hard now - got 2 Maximus tho! 😁 can go to heart, lungs, other organs too . It’s a wait and see - no cure. And still need 5mg of Pred. A day to take edge off pain. It gave me an active life - I’m grateful in spite ( Do take other RA meds too - potencies IV, methotrexate cymbals, Tylenol daily.). Do you know this condition? Never met anyone else-
