Most of the people that I have seen or treated for plantar fasciitis, the person experiencing heel pain cannot pinpoint a specific event that caused the problem. Usually there was some kind of change in their activity that occurred several weeks or months prior to the onset of the heel pain. These changes could be increasing mileage for running or walking workouts, weight gain, walking barefoot on the beach, working long hours on your feet, climbing ladders and the natural process of aging. My advice is don’t spend to much time focusing on how you developed the heel pain, focus on correcting the underlying factors such as poor shoes, inappropriate orthotics and biomechanics.
