After my 3rd infusion of Reclast I experienced sudden neck, shoulder, back bone pain and a level of fatigue that changed my normal active life for 6 months. The pain ended as suddenly as it started. I took a 2 year break from treatment and now need to restart. There is no acknowledgement that this terrible life changing experience had anything to do with Reclast. I understand exactly what I felt. I’m told I should take some Tylenol if I feel some discomfort. As I’m reading here about Reclast Support Groups it makes me angry to see so many patients ignored. There does not seem to be any authorized data collection. I didn’t think there are will be any answers to the side effects until the patent runs out. Doctors can only work with empirical data. And no one is taking with information seriously.
