I have also always had very flat feet. The
pain is in the upper portion of my right
big toe, and seems to be located throughout the upper joint. It also sometimes feels as if there is maybe an extra bone at the bottom of that joint as well, but I can not feel it with my hand, it just feels like I am stepping on a rock or something, inside that joint. To rap things up, I have also been walking more than I did before, as I am trying to loose some weight.
