When I was still doing car audio, I had a bout with PF and it sucked. Since it was Summer, I was also playing softball and since I occasionally played behind the plate as well as on the mound and 1st base, it really sucked. Every time I got up from a squat, it felt like someone had beaten my feet with a baseball bat. At work, I could get some relief by sitting on the counter with my feet hanging down, but it was back with a vengeance when I hopped down to the floor. I tried heel pads, since that's where most of my pain was located, but they didn't help. I was working on a car and realized that I was putting a lot of stress on my foot as I sat on the door sill and forced my toes upward, toward my shin. I decided that I needed to stop doing this and the pain stopped soon after.

Squatting isn't a good thing, especially for someone who has done our kind of work. Kneeling with stress on the toes isn't good, either.
