I had my second round of Evenity injections. Despite years of on and off fosamax both my hips and spine numbers continued to worsen. Other than a slight rash which cleared up in two days, I have had no side effects. I am very diligent about drinking lots of water and get plenty of exercise (walking, water exercise and some specific exercises for my back and shoulder). The duration of each injection is about 20 seconds and stings a bit, but I am already used to it and the nurse is very good at administering.
