Severe pain around right lateral cuboid bone, but no bruising or swelling

Let's see . . First you ran, notice pain, but continued running. Then you ran again the next day, the pain returned, yet you still continued to run and did so in an abnormal fashion to be able to continue. Now painless running, much less walking is not possible and your situation is getting worse, and, instead of seeing a doctor, you are trying to get well from information gleaned on the Internet from people who cannot examine you. Does something sound very wrong with how you are dealing with this problem to you as it does to me?
THIS is not a doctor's office and it is not intended to be one. Find one, with a good doctor in residence.

 

I had the same problem, but i was running 10 miles and the pain just came out of nowhere, now I have a lot of pain just walking. I went to the foot doctor, had x rays and he checked all the tendons. Everything was fine, he believes it is a bruised cuboid bone, and says it should be fine. Told me to get some orthodics for my shoes to stop the pronation in that area and gave me a prescription for some pain relief.
