@sandrajhunt, I just have to comment regarding spontaneous fracture due to osteoporosis. The comment from your physician is accurate. I have severe osteoporosis and last year I had a fractured tibia and ankle after walking several miles, which was considered “overuse “, and required surgery. 2 weeks later I was getting up from a chair and fractured my patella which required surgery. These were both spontaneous fractures second to osteoporosis. So it happens and impacts quality of life.
