This happened a week ago. I was walking and fine then the pain began and I barely made it home. The pain is on top of my foot just above the toes. It is so painful I can barely stand to walk. I was not doing anything but walking so I doubt it is broken. I have wrapped it, soaked it, rested it, nothing helps.
you should see your doctor about this as soon as possible as it could be stressed muscles or ligaments and must be fixed quickly.
