After three years on this drug I have had a lot of hair loss and terrible numbness in my toes. The numbness was toward the end of the day when I would sit down. Until I began to read what others have had to say on this web site about numbness of the feet and hair loss I had no idea that Fosamax was the cause. I did not experience these symptoms until I had been on the drug for a couple of years. My homeopath told me to read about the side effects of Fosamax on the web and that is how I found this web site.
