On February 15th I had a Reclast infusion after completing a year on Evenity. I requested and received a slow infusion of 45 minutes and prepared and followed up with the Tylenol and hydrating that has been recommended by others on this site. At the suggestion of the infusion nurse I also took Claritin for several days. I had the infusion in the late afternoon and had no symptoms until the following morning at 2:00 am when I woke up with a bad headache and some general aches in my upper body for which I took some Tylenol. The first day I was very tired and took three naps but that lasted only one day. For several days my left arm (infusion arm) felt like a torn muscle that I once had in the other shoulder. This went away but on about day 5 my hands became really swollen unrelated to any change in diet. I contacted my doctor as that didn’t seem to be a usual side effect and he said to report back if it continued – it did not. I would say that now at day 11 that I have mild aches which I might be able to attribute to the Reclast but cannot be sure as the areas are the usual suspects (arthritis in hands, etc). On another note, someone else mentioned that they had tried Wellen which is an exercise site devoted to people with osteoporosis. I have been using it on a trial basis and am really impressed. It is very well organized, sessions limited to 30 minutes, geared to the props that you already have on hand, can be reviewed by you before you begin each session and can be adjusted to decrease or increase difficulty. You can sign up for a two-week free trial and if you like it, it is $114 for the year which seems reasonable to me. Thanks to whoever suggested this as I have been searching for a program to accompany Pilates which is pretty expensive.
