@ncgal - It sounds like you are doing good tapering off of the prednisone. I'm also 78 and have thin skin which is easily bruised if I bump into anything. My nails weren't too good until I started taking collagen and I was hoping it may help the skin a little too. I think I may be due for a bone scan also since I was diagnosed with osteopenia several years ago and am supposed to be on 1200 mg calcium daily. I chose not to take it because it was causing some bad constipation so I've been working on my diet to get more calcium.

Can you provide an update after your bone scan?
