Concerned about level of pain from others who have had this type surgery?

I am due to have in two weeks surgery for a neuroma, bunion repair and tarsel tunnel repair on my right foot. Will later have the same done on my left foot. Never having had foot surgery and having a low tolerance for pain :( I am concerned if it is going to be off the charts. Also am concerned about how I can get around the house. I have never tried to use crutches. I am 64 years old and have also never used a walker. I developed this condition 7 months ago from over-doing at a new exercise machine.
