I feel for you, Rayhanah. I always thought I looked a bit like a blowfish when I was on higher doses of prednisone. I still feel pretty puffy (at 10mg) but when I see pix of myself on 40 mg - WOW - I was one moon faced lady! Yikes... So, it does get better - maybe not completely better (as Saysusie says, everyone is a little different) but it DOES get better. Keep doing what you can to exercise - you'll feel better for it, even if it's just 15 gentle minutes.
