I had a similar situation about a month before I ran a half. Sharp pain on the top of the foot, right along the bone, but when you push on it later, it doesn't hurt, right? I went to my doctor (also specializes in sports medicine) and she didn't think it was a stress fracture.
I researched more online and found suggestions to re-lace the shoe. I skipped that section of the top of my foot- keep the crisscross pattern, but just skip to the next set of holes on the shoe. It worked! No more pain. I suspect that the shoe was pressing on a nerve when I was running, which is why it didn't hurt later.
I hope you find a solution! Good luck on your race in Feb. Are you by chance running the Disney Princess?
