I was on Evenity for 6 months when I decided to discontinue. I experienced pins and needle sensations that primarily in the upper arms and lower scalp. Subsequent doses only increased side effects of fatigue, brain fog headaches and random muscle spasms. I also had a significant increase in blood pressure that spiked about 4 days after the injection. I also started to have nerve pain in my fingertips. I do feel there may be a neurolgical component to this medication that has not been addressed in the research. Evenity does build bone, but at what cost?
