Thanks for your concern. I tried the Prolia first, and got an ear infection that lasted 3 months. My doctor said to never get it again, because Prolia hijacks your immune system to build bone. The manufacturer doesn't tell you this, just that Prolia can cause infections, or I never would have tried it. The day after the shot if leaned over to get something off the floor and got really dizzy and almost fell. That was the ear buildup starting to happen. So, if your are susceptible to infections, don't get Prolia.
