I currently have a sharp pain on the top right of my foot?

I currently have a sharp pain on the top right of my foot. I am currently trying to lose weight and have been working out. It hurts when I stand or rotate my ankle. I am unsure what is going on. I am trying to stay off of it but I have a job that requires me to walk for long periods of time. Please help if possible.
