I had my first aclasta infusion 2 1/2 months ago and in the last week I have been experiencing pain in my hips, shoulders, back and neck. I do have arthritis, as well, but my husband is convinced my pain is related to the aclasta. I tend to have reactions to every drug I take (could not tolerate oral osteoporosis meds) Is my pain likely related to my infusion? How long might this last?
