Pain on left heel, inside, right on the edge of my heel. Painful throbbing, sharp, almost prevents me from walking. I pound around for 8-9 hrs a day at work. When I take my shoes off and put my foot on the floor, the pain is excruciating when I lift my foot up off the floor! I have an appt with foot Dr middle of Sept. Been to therapy, bought special socks to keep foot pointed up at night when sleeping, Advil. Nothing helps!
