Stepped on a rock while running

While I was running I violently stepped on a rock about the size of a baseball. It was my right foot almost directly in the sole, closer to the heel and right side of my foot. I shook it off quickly, but as soon as I got home I was in real pain just walking. There is no swelling and I iced it, but I am in a lot of pain even when I try walking. I'm fine as long as I am not putting any pressure on it. Should I go to the doctor or will I be fine soon? I am afraid something may be broken, but I know I probably couldn't walk it that were true. Any help would be greatly appreciated.
