Jan,
Do not push too hard, too fast. If possible, have a PT work with you. Begin by doing light stretching and strengthening. I found crutches to be more useful than a walker when I was allowed to partially weight bear. My foot/ankle are taking longer than my knee to adjust and stop hurting. Again, stretch and be consistent. Just don’t do too much too soon.
You will find much information on this site. Be sure to browse–including thread on foot pain.
