Hi Iheardyouthefirsttime, welcome and thanks for your question.  Boy I sure don't know why someone would ask you that question three times.  I wouldn't worry about it though there's probably a simple explanation for this, that you aren't aware of.   Since your bone density sounds really good I would just wait to talk to the Dr. about your recent results and then ask the Dr. why someone would ask this question.  I suppose there is a "slight" chance that the technician saw something unusal that may have looked like a fracture, but I still won't worry about it since there's any number of reasons she could have ask this question multiple times.   Good luck I hope you get a great report.
