Injury while dancing, quite reccurrent

I have a major competition coming up on Friday, I am competiting in a national competition. I have quite severe pain along the sides of my feet, from vertical to me heel, right along the edges, and it hurts quite a lot when I dance. I injured my ankle while competiting last week, went to the hospital, and they said it was just soft tissue damage. The ankle seems to be holding up at the moment, however I also have pain along the tops of my feet down both sides, and it is a little swelled, and my veins can be seen quite clearly. Any help or advice? Hopefully going to see a Physio tomorrow, but any ideas on what it could be? Thanks in advance.
