Herbie, I had mine done on Oct 22nd. Use your walking stick. You'll need it for another 4 or 5 weeks yet. Try to walk small distances without it, but use it when you feel the need. You've only been out of hospital for 3 weeks so I'm sure you still need your stick. I used mine for most of the 13 weeks recovery, although towards the end of that time I only carried it in case I thought I might need it. Stay with it and don't try to do too much. You'll be fine if you don't try to over-do it.
I'm back at work now and doing ok. Good luck Keep us posted on your progress.
