Hi, Definitely stay away from Prolia. It has ruined my life! It made me lose hair and my legs were in constant pain and my finger joints developed large bone spurs. I felt awful most of the time. All of the osteoporosis drugs have side effects and I am now on calcium, vitamin D and vitamin B12. I keep active but do no formal exercising other than walking - about 2-3 miles a day in the course of my day. Good luck, Kaye -80 yrs. old
