I had horrible side effects that lasted over a week. The first day after the Reclast I got the flu symptoms, but it didn't last long at all. Only a couple of hours. Which was a good thing because I had an hour's drive through the mountains to get back home. Then the following day my right ankle swelled up and I could barely put any weight on it. The day after that the left ankle swelled. Then my right shoulder tensed up and the pain followed. My right arm and hand became so weak the I couldn't lift anything up or even open a bottle of water. Then the next day the same thing happened to my left side. It took me an hour to get myself off the bed. I had no strength left. I could barely walk much less lower myself unto the toilet. It was horrible. Finally the effects wore off and I was so grateful for that. No one told me not to drink caffeine or to hydrate before I go in to get the Reclast. I was told that the day of. I've had a few of the symptoms come back, but not for a few months now. Sorry you went through this. I feel your pain.
