In reply to dan bulman:
I've got one on each foot. Early winter season is always painful until boots and feet get in sync with each other.
Went to docs, didn't get any advice at all really. Dad had one taken care of years ago - horrific; breaking and shaving of bone were involved...
I blame 1990's tight climbing shoes personally! If I go rock climbing, it generally takes a couple of days from the pain to subside...
