I have had 2 Reclast infusions with fortunately less side effects than others. I just had my 2 year scan and my bone mineral density improved substantially, to the point my endocrinologist has paused the infusions until another scan indicates possibly another infusion at some point. I asked if the pain in my lower legs will get better, she advised that I take slow release magnesium at night. I’m sharing this because the Reclast did work for me, but I too experience pains and aches . Mine have been tolerable, drink lots of water , 8 hour Tylenol seems to help and I will see about the magnesium, I just started that .
