But it is absolutely how broken bones are diagnosed! We don’t run around randomly x-raying the population. We have ERs and similar places where those who are hurting go and there we try to answer what is the cause of their pain. If you have a bone broken but its not causing pain and not affecting you in any way how would we even know it? Now this is vanishingly unlikely with broken bones, thus not something we have to worry about much consciously.
