Starting yesterday afternoon I have a sharp pain in my foot which makes it difficult to walk. The pain is right about the top of the fifth metatarsal bone, right on the outside of my left foot. On Saturday I had accidentally stepped in a crack and the side of my foot twisted. It was extremely painful for a minute, but the pain went away. The next day I played 2 hockey games without any pain. Yesterday morning I ran 5k, also with no pain. The pain began yesterday afternoon right in the same spot I stepped into the crack on Saturday. Unfortunately my doctor can't see me until Saturday, so in the mean time I am stuck trying to self diagnose. Everything I've been reading sounds like it could be a fracture, possibly an avulsion fracture of the fifth metatarsal. But what doesn't make sense is if it is a fracture why did it not start hurting until yesterday afternoon? I didn't put much stress on it other then running in the morning. Anyone ever have similar problems?
