Hi, marylemons,
I was put on Fosamax 2 months after stopping Evenity. After 1st dose, I had some stomach issues and joint pain, but that was expected. Three days after the second dose I developed headaches with visual auras. These headaches occurred daily for 2 weeks. I never had headaches with this frequency before. The doctor sent me for a CT which came back ok. I was then referred to a neurologist. By the time I could get an appointment, the headaches were gone. Right now,I am not on any prescription medication. I'll see the rheumatologist in a month and I'm due for a new dexa and bloodwork. Another commenter said the headaches could be due to low blood calcium levels. All I can say that I haven't had a headache since I stopped Fosamax.
