I am interested in this discussion. I have only had 2 Prolia injections before having a severe rash at my injection site. I switched to Alendronate and have taken it for 7 mos. I want to get off this and am taking it until my bone scan in Dec. ( I would go off it right now but scared of the rebound . I just do t feel like I can do this any more. I have IBS and my rhumotologist wants me to try injections but I am not going to do that again. My t scores were -4.2 My hips and 3.5 femoral.
