I've sprained mt foot befre and my ankle. This just feels weird. I was walking in platform heels and i stepped on a curb and twisted my ankle. It dident hurt for about a block of walking but then i started to feel pain on the ball of my foot. its just increased over the past few days. my ankle is fine but the ball of my foot is killing me. the pain comes and goes, but i've been walking on the side of my foot for hours to prevent pressure on it.
