I had the exact same problem for about two years and I was sure that it was plantars fascitis. The pain didn't really move around that much but it radiated up my calf all the way to my hip. I had problems walking for a while.
I have been doing a lot to try to detox and after iodine therapy and eating coconut oil every day for about a month it completely went away. I think there might be other ways to detox that would improve your situation and humaworm is definitely one of them. I'm not sure if the cause is candida, parasites or what, but I would say that it probably isn't bone spurs. Around that time I had a stubborn corn that disappeared as well so you'd be surprised how interconnected the whole system is. Maybe you could look into a liver flush also. If your system is clean, your body can focus on more than necessary functions and detox instead.
