If you have broken a bone due to Osteoporosis are on Medicare and have Parts A & B along with a Supplement, I believe that it will be taken care of. I have broken bones in my back, and have all of the above. I could not get surgery due to my Osteoporosis so I am enjoying getting the injections. I have some fat on my arms so most times, I feel very little of the shot. If you are a skinny person with a lot of muscle, I don't know about.
