I have had several crush fractures in my spine and am in constant pain. My specialist ordered me an IV (infusion) of Aclasta (Novartis). I had terrible acute side effects of pain after taking it but that has now settled. But my usual pain seems to be much worse than before I had the infusion. Has anyone suffered long term effects of having this IV infusion - I can't take it out of my body and it lasts a year. Thanks.
