I went in today for an x-ray to see if I have a stress fracture in my back, but I've been hearing from a few different people, including one of my teammates who has two stress fractures in her back, that stress fractures do not usually show up on x-rays, and that bone scans are sometimes needed to show them for sure. I was just wondering how common this was and why it might be? Are they just so small sometimes that it doesn't show? It doesn't seem very useful to take an x-ray if they don't show stress fractures very well. Anyway, that was my question, sorry if it doesn't make very much sense Oh, and just a disclaimer, I'm not looking for medical advice on my back, I've gone to my doctor and will being going to an orthopedic doctor once the x-ray results come in, I was just wondering what could cause stress fractures to not show up on an x-ray and how common that is. Thanks
