Sooo, the scoop...
He is doing well, walking around his hotel room now with only one cane and walking with canes instead of a walker for distances. Tomorrow he will move from his special spring and arm canes to regular canes. He said that right away his feet changed color and were not cold anymore, and that his fatigue was lifting. He said every day he sees small improvements.

I don't have medical specifics but hopefully I will do when he is home in a week and I can see him.

Thank you all so very much for your kind words.

I will let know as it happens...
