frustrating

Has anyone got soreness on the bottom of their feet from using the treadmill? I have been so good about it and it is so frustrating that my right foot is so sore from the pressure. I went to a foot doctor today and she said that I have sensitive skin and thin feet so they will brooze easily and that I should wear 2 pairs of socks when working out, etc. She banadeged it up to take off some of the pressure in the sore spot but it really hurts when I use the treadmill, caused me to walk a little funny to put pressure on the pinky side of my foot, and it is so annoying. I hope it heals even though I am going to continue going on the treadmill every night.
