I broke a bone in my right foot three years ago and it took a year or so to actually heal but still had some pain occassionally. Last summer my right heel started bothering me to the point that the pain was awful if I walked much at all. I went back to my doctor thinking it was related to the original broken bone. He xrayed it and didn't see a problem and diagnosed it as plantars fasciitis. He gave me a traction boot to wear while sleeping. I was amazed that after a few nights that 90% of the pain was gone. I wore it for maybe a month or so then quit using it. I haven't had any more problems and have no idea why it hasn't returned since I haven't been using the traction boot for months. The boot was a miracle cure for me.
