I dropped a stroller on my foot and had a really nasty pain that would come and go. I needed to wear a plastic boot for 6 weeks. Then 4 weeks of pt. Turned out, I chipped a bone in my foot and the fragment was pressing up against another joint. I had some ligament damage as well.
First of all, go to an othopedic dr. Personally, I wouldn't go to a podiatrist. Also, get it properly treated. If it's broken, the longer you go without attending to it, the worse it will get, and possibly, the more intervention you will need.
