So… A subluxated cuboid bone. That’s what the physiotherapist thinks I have. It certainly fits the symptoms. We ruled out the whole “plantar fasciitis” because my pain is on the outside of my foot, not the arch. I had a couple X-rays this afternoon to hopefully rule out a stress fracture. (There’s something unsettling about a medical procedure so dangerous that the technician has to stand outside the room while it’s performed.) In the meantime, I’m to keep it iced and lay off the running. The physio also showed me how to tape it up, while seems to help a little bit. I guess it’s back to weight training for the time being!
