Hi A.,
When my daughter was about 15 months old she was running through the house, missed the step going down in between the kitchen and living room and ended up at the hospital. She was unable to walk but her foot did not swell much. They did not do an x-ray at the hospital which they should have but sent us to her pedi the next day. Thankfully, her pedi did an x-ray and saw that it was indeed broken. Apparently, because it did not swell or bruise much the hospital didn't feel that it was broken. She could not walk but she was not crying over it either. Due to my own personal experience I would take her to the doctor. It might not be anything at all but at least you'll have peace of mind. Good luck!
