CTB23, my endocrinologist today at my appointment recommended Fosomex since my "numbers" have been going down on my bone density tests. How did you tolerate it? He told me that 1 in every 40,000 develops a hole in her jaw and that a very few experience spontaneous femur breaks. Yikes! He said rare and still better to treat. The other injectable treatment had something to do with the immune system and so he wants to avoid it. Why couldn't you tolerate Fosomex?
