I have been getting a pain in the ball of my left foot when I wear heals. It's the sort of pain you get when you have been wearing heels at a party and danced all night ( if my memory serves me right). I know the answer is not to wear heels but I don't wear them all th time. I usednto wear them constantly before I had dd1 4 years ago with out problem. I am just a little confused as it is only in one foot. Has any one else experienced this.
