I'm sorry to hear that you are in pain and losing hair. I hope that increasing your Prednisone will help to ease some of the pain. I'm not sure if it helps the hair loss or not, may have to just wait until your symptoms subside before you see re-growth again.
I am glad that your Christmas was nice and it was so sweet of you to have your husband's mother. I imagine that time with her, now, is very precious to both of you.
Please continue to take care of yourself and I do hope that you start to feel better very soon.
Peace and Blessings
Look For The Good and Praise It!
