Horrible pain it just doesnt leave with anything....help?

There are a number of muscles and/or tendons you could have tightened up to be giving you that pain. It is going to be around until the muscles are freed up or the muscles released. You didn't say where in your foot the pain is, back, front, side, top, bottom? Each one could lead to a different muscle group as the problem so not knowing where the pain is makes it hard to help you out.
