Stay ahead of the pain! This will help a lot. Alternate tylenol and ibuprofen, maybe even a pain pill at bedtime.
I guarantee you that at 10 days, my unassisted walking was measured in feet, not blocks. By a month I had left the crutches behind (wrist arthritis prevented use of a cane) unless I was out in public- then it was to keep from getting knocked down.
The tiredness is your body healing- rest as you can.
