I had my 1st Reclast Infusion 18 days ago. I was fine until around 3 AM in the morning when I woke up with low back pain and felt feverish. Took my temperature which was 101.8 F; covered the temp with Tylenol 1000 mg, and every 6-hours. By daybreak I ached all over, headache, chills, and fatigue. It was encouraging to read the symptoms may last only 3 days to 2 weeks, but I'm past that and still feeling achey, and very tired. I drank plenty of water before the 15 minute infusion and after. I understand from what I've read, not from my provider, that symptoms can linger longer than 2 weeks. I'm taking Vit D3 and Calcium as prescribed. I discovered from a friend that she had aches and pains, fatigue and headaches on and off for six (6) weeks post infusion. If they want me to do another Reclast Infusion the provider needs to give me an Rx for Vicodin to help address and alleviate the persistent muscle pains. I can't get any rest and some nights suffer insomnia, restless legs; having to cat nap during the day. I'm hopeful this will go away soon and I can feel normal again. Going to try an epson salt bath, maybe absorbing some magnesium will help.
