I did make an appointment to see him after I had decided against the 4th shot, and he said he wasn't concerned because my hips are not as bad as the spine. He asked me to get a DEXA when it is due in May, and that we would go from there. I asked about rebound fractures which occur in a certain percentage of those who stop, and as with side effects, he denied that any of his patients had ever experienced one. This is a doctor in a very large practice, in a major metropolitan area, and one who has specialized in osteoporosis for years. It is rather stunning since rebound fractures are addressed in the Prolia product monograph. There are other physicians in the practice I could see, but that is awkward. I am feeling a little at risk right now in that my bone condition is more precarious than it was when I started. I am paying very close attention to diet, supplements and exercise.
