Re: crushed heel bone
The doc will advise how much weight you can bear. Some people are partial some 100%. Twelve weeks seems to be common for 100%. Therapist will work with you.
You won't just switch to walking either. Atleast I didn't. I broke femur on one side and heel on other. I was in wheelchair. Would use walker a bit, then back to wheelchair, eventually you give up the chair. Used cane and walker for a bit, then just cane, then no cane.
You will know, especially if there is something you really want to do. I was riding motorcycles, just shy of 4 months. I would sit on it. Try to get it up. Try to operate the brake. Then finally did it.
