I had a debilitating back pain for over couple of months before starting Evenity ( on July 2). After week I had a rapid heart beat and dizzy spells. For a couple of weeks. I was going to therapy which never helped for my pack pain. My doctor advised me to do bone scan. I just found out that I have two very new stress fractures. Just guessing that I got them in therapy. The nature of my back pain changed from stabbing to burning and my legs are very weak. I had previously compression fractures and those are healed. Anyone having stress fractures and how to deal with pain because therapy is out of question at least for now.
