Yes. See a podiatrist immediately. Not a regular physician. Podiatrists are really good at this sort of problem. This is potentially serious. The pain suggests infection, and the metatarsal bones are nearby. It could be a clot, but you need a professional look-see. If the infection migrates to the bone, you develop osteomyelitis, which is a nightmare on elm street, and may require weeks of intravenous therapy..
