it’s a nightmare and I hope the boots help. Do they have good arch support? Are you doing stretching exercises to help ease the tension in the tendon?
I had to be off work for nearly a month because I simply couldn’t walk without pain. I had a stand up job on tile floors. When I finally went back, I had to get special permission to wear non-compliant Orthoheel tennies that would help ease the pain.
I hope you can get over this before long!
