my dr is wanting to put the total dose in 1 shot instead of the usual 3,,,we are trying to postpone a shoulder replacement which he really wants me to do,,I have osteoporosis as well as arthritis and have had prolia shots but quit them last oct. medicare will not pay for this so it's out of pocket,,,I'm wondering if Im wasting my time. He says I have bone spurs as well as severe osteo arthritis in shoulders that are deformed.
