<p>Can anyone tell me why some of us have BAD reactions to injections ?<br />My trouble started when I got PMR 4 days after having a high dose flu shot b/c I was 65 . I was shocked. I took prednisone for 9 months but got PMR again 6 years later . Today I have a -3.8 T score in my lumbar area . My orthopedic wants me to start prolia but I am afraid . I don’t think that the suggested doses are for all . I did not get a covid vaccination because of the same fear . Should I see an endocrinologist to talk about my fears of these high dose injections that cause so many people much pain . Can someone tell me of a good experience that they had with prolia ? I now am nearly 77 but am reasonably active and healthy . Thank you</p>
