Re: Had surgery--NEED HELP!!!!
After my surgery I started walking at 6 weeks. It was still several weeks after that that I kept it up as much as possible. The numbness can take quite a while, but should get better eventually. I was numb in between two of my toes and it finally came back after a few months. I am still numb in the 1 inch area around the incision. It depends on if the numbness is due to cut nerves (like around the incision) or compressed nerves from swelling (probably the rest of your foot). The compressed nerves will come back faster, the cut nerves may never come back.
The feeling of walking on rocks may be due to shrinking of the fat pads in your foot as well as losing your callouses from being in the cast and not putting any weight on the foot. That was my biggest complaint when I went back to shoes from the boot. I walked 1/2 mile and my ankle felt fine, but my toes were killing me because they were rubbing on my shoe! That should get better over time.
As for going back to work, it's your call. If you need a doctor's note to stay off work longer, discuss your job duties with him and tell him you don't feel that you can start working yet. You could consider getting one of those things that's a substitute for crutches. It's like this platform with a handle that your roll around on. Or you could just use an adjustable-height rolling office chair. That way you could kneel on that and not have to deal with crutches or have the foot hanging all the way down all day. Good luck.
