It might be a bit late for that now though, since the injury occurred last Wednesday, but it might help with the pain
. Is there any noticeable/visual deformity on your foot
? It would most likely be too painful
for you to walk on it at all if you broke your foot, so I doubt that is what is going on. It could be a fracture, tendon problem, RSD, etc., but it's hard to tell without having an x-ray or other diagnostic tool/visual.
