This is what a bone scan image of a tibial stress fracture looks like. After two months of pain (and denial) in my right shin, I finally know exactly what's wrong. I went to the doctor about a month ago, and he recommended easing back on my running. With the Boston Marathon just weeks away, I cut back and focused on cross training. In the two weeks leading up to Boston, I only ran three miles. I haven't run at all since Boston. When I got home from the race, I called my doctor and asked to get an X-Ray of my leg. It came back clear, but because my leg wasn't getting better, he ordered a bone scan. As soon as the image came up on the screen, I was pretty sure it was a stress fracture since there was a glowing white spot in the exact place of my pain. It is still sinking in that I won't be able to run for 4-6 weeks. Today has been a roller coaster of emotions. But I'm trying to be positive. I am trying to focus on the fact that I finally know what is wrong
