This is something you might want to try Warning I am not a doctor. Do not take this as a diagnosis. I had a similar pain years ago and a friend who is a physical therapist told me to sit in a chair. place a tennis ball in a thick tube sock and put the sock on the floor. Then while sitting, massage your foot by placing your foot onto the ball and roll the ball around with your foot applying gentle pressure so you feel a little stretch BUT NO PAIN. be sure to focus on your arch.
